INTRODUCTION

This is a key to the Club-shaped Fungi of the Pacific Northwest (British Columbia, Washington, Oregon, and Idaho). Club-shaped fungi as understood here include the upright, unbranched fungi that do not fit into other morphological groups. There are not only clavate (club-shaped) fungi, but cylindric fungi, and upright fungi with differentiated heads.  Both ascomycetes and basidiomycetes are included.

This way of defining clubs places them in a fourteen part morphological classification of non-gilled fungi: 1) boletes, 2) polypores, 3) toothed fungi, 4) veined fungi, 5) cup fungi, 6) morels and false morels, 7) puffballs (and earthballs, earthstars), 8) truffles and false truffles (including the sequestrate fungi in general), 9) coral fungi, 10) club fungi, 11) jelly fungi, 12) crust and parchment fungi (including the jelly fungi that grow as crusts), 13) bird’s nest fungi, and 14) other.

The species are divided into seven groups, the first six characterized by the color of the upper part of the fruitbody, and the last containing the stinkhorns, distinctive species which distinguish themselves immediately by their foul odor. Species that have more than one color are included in more than one color group. The key leads start at the following numbers.

	Yellow to orange	101
	Purple, pink, red	201
	Green	301
	White to whitish	401
	Black	501
	Brown	601
	Stinkhorns, various colors	701

KEY TO SPECIES
__________________________________________________________________________________

YELLOW TO ORANGE
__________________________________________________________________________________

101a	Firm-gelatinous consistency, slippery surface, bright yellow to yellow-orange, less than 1.5 cm tall, on or near wood	Calocera cornea

0.2-0.7(2.0) cm x 1-2 mm, awl-shaped to cylindric, or forked, firm-gelatinous, yellow to orange-yellow, smooth, lubricous. FRUITING on dead barkless hardwood or conifer wood. MICROSTRUCTURES basidiospores 7-10(12) x 3-4.5 um, 1-septate.

101b	Firm to fragile but not gelatinous, surface moist to dry (or if gelatinous and slippery then associated with pools of water or streams), various colors, sizes, and habitats	102

102a	Bright yellow or bright orange fruitbody, without distinct head separated from stem, or head forming most of fruitbody	103

Note: In the Pacific Northwest, most of these will be Clavulinopsis laeticolor. Clavulinopsis fusiformis, Clavaria gracillima, and Neolecta vitellina could look similar, but suspect C. fusiformis if fruitbodies are tall or in tight bundles or taste bitter, suspect Clavaria gracillima if the upper tips are whitish (= Clavulinopsis luteoalba (Rea) Corner), and suspect Neolecta vitellina if fruitbodies are spatula-shaped or particularly irregular, or pale yellow in color. Microscopic confirmation is straightforward. 

Mucronella pulchra differs markedly, consisting of tiny, yellow, hanging, waxy fruitbodies.

Clavulinopsis corniculata can occasionally be unbranched (forma simplex Donk). Its spores are 4.3-7.2 x 4.3-7.2 um (similar to C. fusiformis) but the unbranched form is slender, about 1.5-2.5 mm wide and it grows singly or in small groups, whereas C. fusiformis is 2-10 mm wide and grows gregariously or densely bundled. Clavulinopsis helvola (Pers. ex Fr.) R.H. Petersen may occur in the Pacific Northwest (for example a collection at Oregon State University as Clavulinopsis helvola) and has spores that are often angular and measure 4-7 x 3.6-6 um excluding warts that are 1-2 x 1-1.5 um.

102b	Dull yellow to orange or yellow-brown to orange-brown, distinct or indistinct head	104

103a	Common, up to 10 cm tall, may be in bundles, color yellow to orange-yellow, taste mild, basidiospores 4.3-7 x 3.7-5 um	Clavulinopsis laeticolor

1.5-10 cm x 0.2-1.0 cm, usually about 3-4 cm tall, often somewhat flattened, fusiform (spindle-shaped), or with rounded blunt top, or branched once, lemon yellow to orange-yellow, finely wrinkled, smooth to bald. TASTE typically bitter but sometimes mild. FRUITING single, scattered, in groups or cespitose on the ground. CHEMICAL REACTIONS spore-bearing surface dingy greenish in FeSO4, yellow-green in KOH. MICROSTRUCTURES basidiospores 4.3-7 x 3.7-5 um, ovate or rounded-triangular, smooth, slightly thick-walled, prominent apiculus. REMARKS also known as Ramariopsis laeticolor.

103b	Uncommon, up to 15 cm tall, often densely bundled, color yellow, taste typically bitter but sometimes mild, basidiospores 4.8-7.5(9.2) x 4.5-7.2(9.2) um	Clavulinopsis fusiformis

1.0-15 cm x 0.2-1.0 cm, usually simple club, rarely branched once or twice near top, often more or less flattened, solid becoming hollow, often densely bundled but only rarely significantly joined together above the surface of the ground, tip usually sharp to narrowly rounded; bright yellow, top usually darker in the reddish or brownish shades especially when old, flesh yellow; base whitish, bald, minutely lined. TASTE typically bitter but sometimes mild. FRUITING densely bundled, gregarious, often in troops, on soil, usually in open areas with grasses. CHEMICAL REACTIONS spore-bearing surface gray-green in FeSO4, and orange in KOH (i.e. no effect). MICROSTRUCTURES basidiospores 4.8-7.5(9.2) x 4.5-7.2(9.2) um, round to very broadly ovate, smooth, slightly thick-walled, with stout conical apiculus. REMARKS also known as Ramariopsis fusiformis.

103c	Upper tip may be whitish, (basidiospores 6.0-9.2(11.9) x 2.5-4.5(5.3) um)	Clavaria gracillima

1-8 cm x 1-3 mm, slender, slightly waxy-fleshy in consistency, usually hollow through much of the club portion, top sharp to rounded, apricot to pale pinkish orange, the stem somewhat distinct in its clearer colors, top colored the same or slightly lighter than the spore-bearing part, not turning color when old or bruised, stem often with a very small, white, somewhat bristly patch at very base. TASTE none. FRUITING single, gregarious, or nearly cespitose in 2s and 3s but not bundled, on leaf or needle litter. CHEMICAL REACTIONS no color reaction with FeSO4 or KOH. MICROSTRUCTURES basidiospores 6.0-9.2(11.9) x 2.5-4.5(5.3) um, ovate to elliptic, smooth, thin-walled to slightly thick-walled, small abrupt lateral apiculus; basidia 1-4-spored. REMARKS Clavaria luteoalba and Clavulinopsis luteoalba are synonyms.

103d	Pale yellow, may be irregular in shape, (ascospores 5.5-9 x 3-4 um in 8-spored asci)		
		Neolecta vitellina

3-3.5 cm, irregularly clavate, lanceolate, or spathulate, usually narrowed in upper part, stuffed or hollow, head 0.3-0.9 cm wide, luteous to pale luteous, confluent with stem along an uneven border, smooth, wrinkled or somewhat pleated; stem 0.2-0.4 cm wide in upper part, narrowing below and rooting, frequently rotted off, white to straw or pale luteous, more or less bald, downy, or tomentose. FRUITING on needle beds and moss carpets usually on ravine or hill slopes, August to October. MICROSTRUCTURES ascospores 5.5-9 x 3-4 um, usually 7 x 3.5 um, kidney-shaped, elliptic or ovoid, smooth, inamyloid, non-septate, asci 8-spored, 53-75 um long, paraphyses lacking, phialoconidia regularly associated. REMARKS Description is largely derived from Redhead (1977a). Neolecta vitellina has often been mistaken for Neolecta irregularis of eastern North America and Japan which is wider, more brightly colored, with spores 5.5-10 x 3.5-5 um, usually 8 x 4 um, and asci 100-135 um long, phialoconidia absent.

103e	Yellow, hanging, waxy fruitbodies, 1-5 mm long and 0.1-0.3 mm wide, densely gregarious on wood	Mucronella pulchra

Spines tapering downward from basal attachment, at first discrete, then more or less connected by a subiculum, whitish to orange, when dry pale orange to reddish. FRUITING on wood. MICROSTRUCTURES basidiospores 4-7 x 3.5-6 um. REMARKS Recorded from British Columbia based on Corner’s Supplement 1970. Mucronella flava Corner is also yellow: it has not been recorded from the Pacific Northwest but has narrower spores measured at 4-6 x 2.5-3 um and 4-5(5.5) x 2.8-3.5(4) um. Desjardin illustrates it for California.

104a	(102b)  Fruitbody with a flattened paddle-like head that extends down opposite sides of stem, common	Spathularia flavida

1-8 cm high, spore-bearing upper part flattened laterally, spatula-like or oval or fan-like, running down opposite sides of stem, up to 3 cm wide, pale when young becoming pale yellow to yellow, buff, or brownish, sometimes lobed or contorted or with a notched top, the head forming a half to two thirds the height of the fruitbody; stem 0.2-1.0 cm wide, variable in shape but often thicker at base, white to colored like upper part but usually paler, smooth to finely mealy but not velvety. FRUITING scattered to gregarious or even clustered, on humus or rotten wood under conifers or occasionally hardwoods. MICROSTRUCTURES ascospores 30-95 x 1.5-3 um, variable in size, needle-like, rounded at one end, smooth, with zero to several septa, colorless under microscope but often yellow-brown in mass, the wall with a gelatinous layer swelling to 1.5-3 um thick; one-celled conidia 1-2 x 1-1.5 um may also be present or even replace the ascospores in the asci; paraphyses strongly curved or coiled or straight, colorless.

104b	Fruitbody NOT with a flattened paddle-like head that extends down opposite sides of stem	105

105a	Distinct head by structure or color	123
105b	Head not clearly separated from stem, and tapering down into stem	106

106a	Dull yellow to dull orange-brown, roughly cylindric fruitbody widening somewhat upwards, or strap-like (laterally flattened), 2-25 cm tall, (Clavariadelphus, staining green with iron salts)	107
106b	Various colors; threadlike-cylindric or less than 2 cm tall, or with pimples or pits visible under hand lens; if club-shaped then yellow-cream, if strap-like then gregarious on decaying needles and decaying male cones of Pinus ponderosa)	113

107a	Truncate	Clavariadelphus truncatus

5-15 cm high, up to 1.5 cm wide basally, widening upward to 3.5 cm or wider, club-shaped, then top-shaped or with a depressed or perforated top; sides of fruitbody pinkish cinnamon to orange-brown or yellow-brown, the top usually brighter and yellower at least when young, sides and top smooth to wrinkled, where cut or bruised staining slowly brown; flesh white to ocher, on exposure staining slowly brown, soft becoming spongy; stem base round in cross-section, smooth, white to pallid where covered, otherwise cream color to buff or pale orange; mycelial hyphae loosely interwoven or aggregated into white to pallid rhizomorphic strands up to 1 mm wide. TASTE sweet (Methven 1990), mild to sweetish, or bittersweet, (Arora), not distinct (Castellano). FRUITING scattered to gregarious on soil and duff, under mixed conifers, July through November. SPORE DEPOSIT white, gradually yellowing during storage. CHEMICAL REACTIONS KOH cherry red to fire engine red reaction; tissue dark green in FeCl3. MICROSTRUCTURES basidiospores 9.5-13.5 x 5.5-7 um, broadly elliptic, broadly ovate or almond-shaped, smooth, inamyloid, pale yellow in KOH. REMARKS The top is sterile, like that in C. mucronatus, whereas most Clavariadelphus species are fertile at the top. None of the Clavariadelphus species listed here for the Pacific Northwest has the cherry red to fire-engine red reaction to KOH. C. caespitosus has grayish red to dull red or cinnamon buff fruitbody with top somewhat sharp to narrowly blunt, may taste slightly bitter, and often grows in cespitose clusters. C. occidentalis has pale yellow to pinkish buff or grayish orange fruitbody with top somewhat sharp, blunt or broadly rounded. Clavariadelphus subfastigiatus has fruitbody that is pallid flesh-color to light cinnamon, with top that is blunt or broadly rounded, bitter taste, and green reaction of surface to KOH.

TASTE not distinctive. FRUITING gregarious, terrestrial, on conifer debris and needles. SPORE DEPOSIT white, pale yellow, pale orange, or buff. CHEMICAL REACTIONS no reaction in KOH, tissue dark green in FeCl3. MICROSTRUCTURES basidiospores 10.5-14.5 x 3.5-4.5 um, narrowly elliptic, boletoid or sway-backed in profile, smooth, inamyloid, pale yellow in KOH. REMARKS The spore-bearing surface is on the sides and the top is sterile.

MICROSTRUCTURES basidiospores 18-24 x 4-6 um, narrowly elliptic, boletoid or sway-backed in profile, smooth, inamyloid, pale yellow in KOH; basidia 65-105 x 8-12.5 um. REMARKS Clavariadelphus ligula cannot be separated reliably in the field, but has smaller spores and basidia.

110b	Spores 12-16.5 x 3.5-4.5 um	Clavariadelphus ligula

2-10 cm high and 2-8 mm wide at base, widening upward to 5-12(22) mm, cylindric to flat-cylindric or club-shaped, the top somewhat sharp, blunt, or broadly rounded, rarely forked, fruitbody at first pale yellow becoming pinkish cinnamon to ochraceous cinnamon, finally pale dull brown, staining slowly brown where damaged (or occasionally green at top), smooth to slightly wrinkled; flesh white to pallid, slowly staining brown when exposed, solid becoming spongy; stem round in cross-section, powdery, downy, pale at first, then brownish orange to light brown; mycelial hyphae loosely interwoven or aggregated into rhizomorphic strands up to 1 mm wide, penetrating the substrate.

TASTE bitter. FRUITING scattered to gregarious or bundled in clusters of 6-20, on well-decayed humus of coniferous woods. SPORE DEPOSIT white. CHEMICAL REACTIONS surface stains forest green (or yellow green) with KOH, surface stains forest green to dark green with FeCl3. MICROSTRUCTURES basidiospores 8-10 x 5-6 um, broadly elliptic, broadly ovate or almond-shaped, smooth, inamyloid, pale yellow in KOH. REMARKS Clavariadelphus subfastigiatus is distinguished most easily from close species by the green reaction of its surface to KOH. Clavariadelphus caespitosus has grayish red to dull red or cinnamon buff fruitbody with somewhat sharp top, lack of staining reaction with KOH, cespitose growth, and slightly larger spores. C. occidentalis has light yellow to grayish orange fruitbody, lack of staining reaction with KOH, and larger spores. C. truncatus has pinkish cinnamon to orange-brown or yellow-brown fruitbody with top yellower and brighter, the top blunt becoming truncate, excavated, perforated, or even umbonate, red reaction of surface to KOH, usually sweet or mild taste, and larger spores.

111b	Differently colored, no forest green KOH staining	112

112a	Grayish red to dull red or cinnamon buff initially becoming browner, gregarious, densely gregarious or in cespitose clusters (spores 8-11 x 4.5-6.5 um)	
		Clavariadelphus caespitosus

up to 3-15 cm high, 0.3-1.5(2.0) cm wide at top, at first nearly cylindric, then narrowly club-shaped or spindle-shaped, top somewhat sharp to narrowly blunt; at first grayish red to dull red or cinnamon buff, finally more brown, where cut or bruised staining slowly brown; smooth, becoming longitudinally wrinkled; flesh white to pallid, on exposure staining slowly brown, solid becoming spongy; stem base round in cross-section, powdery, pale to pinkish. TASTE not distinctive or slightly bitter. FRUITING gregarious, densely gregarious or in cespitose clusters, on ground, in duff, in coniferous or mixed forest. SPORE DEPOSIT white. CHEMICAL REACTIONS KOH negative; FeSO4 or FeCl3 green. MICROSTRUCTURES basidiospores 8-11 x 4.5-6.5 um, broadly ovate to almond-shaped, smooth, inamyloid, pale yellow in KOH. REMARKS Clavariadelphus subfastigiatus has pallid flesh-color to light cinnamon fruitbody with blunt tops, forest green staining reaction with KOH, scattered to gregarious growth, and slightly smaller spores. C. occidentalis has light yellow to grayish orange fruitbody, and larger spores 10.5-14 x 6-7.5 um. C. truncatus has pinkish cinnamon to orange-brown or yellow-brown fruitbody with top yellower and brighter, the top blunt becoming truncate, excavated, perforated, or even umbonate, red reaction of surface to KOH, usually sweet or mild taste, and larger spores. 

112b	Light yellow initially becoming pinkish buff to grayish orange, single to gregarious, infrequently in cespitose clusters - usually 2 or 3 fruitbodies in a cluster, (spores 9-13.5 x 5-6.5 um)	Clavariadelphus occidentalis

5-25 cm high, 0.5-1.5 cm wide basally, 1-3.5 cm wide at top, initially nearly cylindric to somewhat spindle-shaped, becoming club-shaped, finally irregularly laterally flattened, top somewhat sharp, blunt, or narrowly rounded, fruitbody initially light yellow, pinkish buff at maturity, finally grayish orange, top the same color, where cut or bruised the surface staining slowly brown; smooth becoming longitudinally wrinkled; flesh white to pallid, on exposure staining slowly brown, solid becoming spongy; stem base round in cross-section, smooth, powdery, white to pallid where covered, otherwise pale yellow to buff; mycelial hyphae interwoven or aggregated into rhizomorphic strands up to 1 mm wide, white to pallid. TASTE not distinct or bitter (Castellano), not distinct (Methven 1990). FRUITING single to gregarious or in cespitose clusters of 2 or 3, on soil or duff in forests, mostly September through February but also in May. SPORE DEPOSIT white to pale yellow, (Castellano), white (Methven 1990). CHEMICAL REACTIONS tissue dark green in FeCl3; no reaction in KOH. MICROSTRUCTURES basidiospores 9-13.5 x 5-6.5 um, broadly ovate to almond-shaped, smooth, inamyloid, pale yellow in KOH. REMARKS Clavariadelphus subfastigiatus has pallid flesh-color to light cinnamon fruitbody, forest green staining reaction with KOH, and smaller spores (8-10.5 x 5-6 um). C. caespitosus has grayish red to dull red or cinnamon buff fruitbody with somewhat sharp top, cespitose growth, and smaller spores. C. truncatus has pinkish cinnamon to orange-brown or yellow-brown fruitbody with top yellower and brighter, the top blunt becoming truncate, excavated, perforated, or even umbonate, red reaction of surface to KOH, sweet taste, and similar sized spores. Small immature fruitbodies of C. occidentalis might be confused with C. ligula or C. sachalinensis, but both have different spores which are narrowly elliptic to boletoid in side view (rather than broadly ovate to almond-shaped in side view for C. occidentalis). Clavariadelphus occidentalis (along with other taxa that include C. caespitosus and C. subfastigiatus), has passed under the name Clavariadelphus pistillaris which is found in eastern North America and Europe.

FRUITING gregarious on decaying needles, and, mostly, on decaying male cones of Pinus ponderosa (Western Yellow Pine). MICROSTRUCTURES basidiospores (7.7)8.5-10.7 x (4.1)4.4-5.6 um, elliptic to nearly cylindric, smooth. REMARKS Clavariadelphus sachalinensis and Clavariadelphus ligula are duller in color, wider, have white mycelium at base of stem which binds the substrate, and have larger spores.

REMARKS Asterophora parasitica, which also grows on rotting Russula and Lactarius, has non-powdery, dirty white silky cap and smooth, elliptic chlamydospores from well-formed gills (therefore not included in this key of non-gilled club fungi).

402b	Not growing on dead mushrooms	403

403a	Growing on dead animal material	404
403b	Not growing on dead animal material	405

hanging, awl-shaped or spindle-shaped spines 3-5 mm long and about 0.3 mm wide, whitish, may be yellowish toward base, soft; short white stem with downy surface. FRUITING in groups on rotten conifer wood. MICROSTRUCTURES basidiospores 5.7-7.4 x 5-5.7 um, obovate to nearly round. REMARKS It is doubtful whether this can be separated from Mucronella pendula above. In redescribing M. fusiformis, Harrison indicates that an A.H. Smith collection has spores 6.6-8.2 x 5.0-6.6 microns revived in water and 6.6-8.2 x 5.0-5.7 microns revived in Melzer's reagent, making any distinction by spore size dubious. Use of the watery character emphasized for M. pendula, the yellowish color in stem for M. pendula, or the downy stem surface of M. fusiformis would require more data.

410a	Funnel-shaped to horizontal kidney-shaped, thin-fleshed cap, often with convoluted margins, upright central to lateral stem	Stereopsis humphreyi

cap single or rarely 2 or 3 per stem, 0.6-2.9 cm wide, becoming kidney-shaped to funnel-shaped, cleft on one side to the stem, often with markedly wavy margins, membranous and soft, dull white on upper surface, dry, silky when young, nearly smooth to wrinkled, later most becoming obscurely zoned-ridged and often minutely cottony-scaly or rough towards stem; spore-bearing surface on the underside of cap decurrent, nearly smooth but sometimes when old with low radiating wrinkles or more prominent furrows, creamy white, demarcated from stem; stem 1-3 cm x 1-3 mm, stuffed to hollow, tough, pliant, white (but when old age faintly cinnamon), velvety, a few bald except at base, base with hairs. FRUITING gregarious on mossy needle beds, cones, twigs, fern fronds, and mosses, in coniferous forest. MICROSTRUCTURES basidiospores 6.5-9 x 3.5-5.5 microns, narrowly to broadly oval to elliptic, smooth, inamyloid. REMARKS This is anomalous among the “club fungi”, but nevertheless fits the definition used here (upright, unbranched fungi that do not fit into other morphological groups).

410b	Not having these characters	411

411a	Fruitbody yellowish ocher to cream or dull brown with convex cap resembling that of a gilled mushroom (without gills) or a shallow cup, wider than it is tall; growing in wet paths or ditches or other very wet places, on wet decaying wood, or other wet decaying plant debris (for description see 130a)	Cudoniella clavus

		Hypocrea leucopus or Hypocrea alutacea

	Note that a very pale young Spathularia flavida could key out here and is a much more common species. For a description see 104a.

FRUITING single to gregarious on dead sticks and branches. MICROSTRUCTURES basidiospores 10-15 x 5.5-8 um, elliptic, smooth, inamyloid, colorless; cystidia not seen. REMARKS Macrotyphula juncea is very thin (up to 0.2 cm thick) with spores 6-12 x 3.5-5 um, and occurs on humus, rotting twigs, leaf litter, etc.

very thin, 3-15 cm high when mature, 0.5-2 mm wide, solid becoming hollow, erect but often becoming bent and twisted, tip sharp or when old sometimes blunt, leather-colored to yellowish buff or orange brownish or pallid, smooth, sterile stem 1.0-2.5 cm long, not distinctly demarcated from fertile part, somewhat darker in color, sometimes with lateral thorn-like outgrowths, base with white appressed hyphae; flesh very thin, firm and tough when young. FRUITING scattered to gregarious on humus, leaf remains, needles, twigs, plant stems, bud scales, etc., in damp places, fall. MICROSTRUCTURES basidiospores 6-12 x 3.5-5.5 um, elliptic or almond-shaped, smooth, inamyloid, colorless; basidia 1-4-spored. REMARKS Typhula phacorrhiza has a sclerotium (like other Typhula species) and has larger spores. Macrotyphula fistulosa is larger, usually 5-10 mm wide at widest point, has spores 10-15 x 5.5-8 um, and grows on dead sticks and branches. A tall example of Eocronartium muscicola could key out here but would be growing on moss (see 418a).

414b	Less slender in relation to height or not as tall	415

415a	Growing on algae or moss protonemata	416
415b	Not growing on algae or moss protonemata (may grow on moss plants)	417

3-20 mm high, 1-2 mm wide, mostly simple, but sometimes forked into 2-6 linear curved ascending branches, or incised or minutely crested at the top, solid, cylindric to spindle-shaped, tip sharp or blunt, delicate but waxy-tough, not breaking on bending, smooth or longitudinally wrinkled, when fresh white, pale cream, yellowish, or even pinkish, the upper part becoming darker or more pigmented or tipped whitish, fruitbody narrowing into indistinct stem. FRUITING in groups but not clusters on wet, algae-covered, rotting wood, according to some authors sometimes also on algae-covered soil. MICROSTRUCTURES basidiospores 4.5-7.7 x 1.8-3.2 um, smooth, colorless; basidia 4-spored; cystidia none.

416b	On soil, pale yellow to straw or pinkish shades, (spores 5.6-8.2 x 2.1-3.5 um, basidia often with more than 4 sterigmata)	Multiclavula corynoides

1-2.5cm high, often somewhat spathulate or laterally compressed toward the top, simple, lobed or branched to somewhat lacerate; pale yellowish to straw or pinkish shades, somewhat translucent, at least toward the base. FRUITING associated with algae on soil. MICROSTRUCTURES spores 5.6-8.2 x 2.1-3.5 um, smooth; basidia 4-5-6-spored. REMARKS The distinctions between this species and Multiclavula vernalis are inconsistently made by different authors, and here we follow Petersen. Note that Petersen does not make a distinction based on color or branching of the fruitbody but instead emphasizes the number of sterigmata on the basidia. He lists M. corynoides for BC, WA, and ID (as well as ON, NY, and Europe). Multiclavula corynoides was thought by Corner to be only the better developed state of Multiclavula vernalis.

416c	On soil, cream to pinkish cream or straw orange, (spores 6-12 x 2.5-3.5 um, basidia 4-spored)	Multiclavula vernalis

up to 2cm tall, unbranched, club-shaped; creamy to fleshy cream or straw-orange when fresh, dull ochraceous orange when dry. FRUITING on the ground, associated with algae or moss protonemata. MICROSTRUCTURES spores 8-12 x 2.5-3.5 microns in description but 6-12 um long in key, elliptic to narrowly oval, smooth, thin-walled, without droplets; basidia strictly 4-spored (rarely less). REMARKS Multiclavula vernalis is yet to be confirmed from the Pacific Northwest using the concepts of Petersen (see remarks under M. corynoides). There are collections at the University of British Columbia and Oregon State University, but it is not known what concepts were used.

416d	On soil, light tan, often branched, (spores 7.5-9 x 2.5-3.5 um, basidia 4-spored)	
		Multiclavula sharpii

10-30 mm x 1-2.5 mm, somewhat compressed laterally, usually lacerated to imperfectly palmately branched, tip expanded; light tan when fresh, drying dingy cream or pinkish buff. FRUITING gregarious, sometimes crowded, associated with algae or moss protonemata, on clay soil. MICROSTRUCTURES spores 7.5-9 x 2.5-3.5 um, smooth; basidia 4-spored. REMARKS described from Prince George, BC.

FRUITING single, gregarious or scattered, under conifers. SPORE DEPOSIT white. MICROSTRUCTURES basidiospores (5.6)6.0-6.8(7.3) x (4.9)5.1-5.7(6.2) um, nearly round to very broadly ovate, smooth, colorless. REMARKS Clavaria americana is a synonym. 

418b	Not having these characters	419

419a	Needle-like fruitbody with little or no stem, 1-11 mm high, 0.1-0.3 mm wide, fruiting on dead stems and leaves in swampy places, not attached to sclerotium, (spores 9-16 x 4-7 um on 2-spored basidia)	Pterula gracilis

		Clavaria acuta

10-80 mm high, 1-3(5) mm wide, vermiform (worm-like) to slenderly club-shaped, rounded in cross-section to slightly compressed, blunt to pointed, white when young (then ocherish-grayish), smooth, fragile, stem 5-20 mm long, often translucent. FRUITING single, in pairs or trios or less commonly in clusters, on bare soil, among grass, or in flower pots. MICROSTRUCTURES basidiospores 7-10 x 5-9 um, broadly oval, smooth, inamyloid, colorless, basidia 2-4-spored with medallion clamp connection at their bases. REMARKS Clavaria fragilis is usually larger, grows in clusters, has the stem the same color as the club, has narrower spores, and lacks the medallion clamp connections at the bases of the basidia.

420b	Not having these characters, usually attached at lower end to a sclerotium (Typhula)	421

421a	Growing on leaves and stems of grasses and winter cereals, sclerotium forming with mycelium often near or under snow	422
421b	Not having these characters	424

422a	Whitish then pink, stem whitish then dingy, arising from sclerotium that is pinkish orange then tawny to dark reddish brown	Typhula incarnata

3.4-30 mm high, but typically less than 10 mm high, single or in small groups from the sclerotium, head 1-20 mm x 0.4-2 mm, thread-like, cylindric, elliptic-oblong when short, becoming hollow, sharp then blunt, color whitish then flesh color or rose-pink, stem 5-20 x 0.5-1 mm, translucent white or whitish cream, then grayish or dingy brownish, downy, sclerotium 0.5-4.5 mm x 0.5-2 mm, nearly spherical, more or less flattened, smooth, drying or aging rough, sometimes irregular, pinkish orange when mature, then tawny to reddish brown or dark brown. FRUITING on dead culms and leaves of cereals and grasses, and on herbaceous stems and leaves, sclerotia in spring usually in snow cover conditions, fruitbodies in fall. MICROSTRUCTURES  basidiospores 4-15 x 2-8 um, elliptic or ovoid, smooth, white; basidia 4-spored. REMARKS This species causes the disease variously called speckled snow mold, gray snow mold, snow scald, or Typhula blight (also caused by T. idahoensis and T. ishikariensis), which can attack cereals and grasses. The name “speckled snow mold” comes from the appearance when snow is melting: patches of "mold" (mycelium) speckled with sclerotia. Typhula incarnata is also found causing a root and crown rot of wheat and barley in the absence of snow cover. Typhula phacorrhiza does not have a distinct head, and is yellowish in color. Typhula idahoensis and T. ishikariensis have different color of fruitbody and sclerotium. None of these species are characterized by the occasional digitate (finger-like) or radiate cells in the rind of the sclerotium that are found in T. incarnata if several fragments are examined.

422b	White or white-grayish or brownish fruitbody, arising from amber to blackish sclerotium	423

423a	White or white-grayish fruitbody	Typhula ishikariensis

3-20 mm high, (0.3)0.5-1(3) mm wide, 1-3 from each sclerotium, spindle-shaped (occasionally flattened), powdery white to watery gray or light brown, head about half to two thirds of height of fruitbody, stem thread-like, darker than the fertile part; sclerotium (0.3)0.5-1.5(2) mm in diameter, spherical to nearly spherical or slightly flattened, light brown to black, surface smooth to rough. FRUITING develops only after prolonged snow cover, it is the dominant Typhula species in Washington on winter cereals grown in formerly forested areas, it also attacks clovers, turf grasses, and several legumes and broadleaved weeds. MICROSTRUCTURES  basidiospores 7.3-9.8 x 2.6-3.7 um, digitate cells rare in rind of sclerotia, (Bruehl (1975), who says these measurements are smaller than those made by other workers). REMARKS Typhula incarnata causes the same kind of disease, but sclerotia easily distinguished by color.

423b	Brownish fruitbody	Typhula idahoensis

5-10 mm high, 1 to several per sclerotium, or arising directly from the mycelium or from stolons from the mycelium and growing on the ground, club-shaped, bright warm brown to vinaceous brown, dark fawn, or gray-brown, the head paler than the stem, head 4-7 mm x 0.5-1.5 mm, elongate-fusiform, often thickened at top, or cylindric; stem 2-5 mm x 0.1-0.5 mm, bald or downy at base; sclerotium 0.5-2 mm x 0.5-0.9 mm, spherical or nearly so, flat below, convex above, chestnut-brown to blackish, bald, shining then dull. FRUITING rarely attacks species other than winter cereals and grasses; sclerotia form with the snow melt, fruitbodies grow in fall. MICROSTRUCTURES  basidiospores 8-13.5 x 4-8 um, ovate-elliptic; basidia 4-6-8-spored, 27-32 x 6-8 um, (Corner (1950)), spores 6.5-9.6 x 2.4-3.3 um, (Bruehl (1975), who says these measurements are smaller than for other authors).

FRUITING gregarious and cespitose, on decomposing fallen leaves of various hardwoods, petioles, herbaceous stems and grasses. MICROSTRUCTURES basidiospores 11-15 x 4.5-5.5 um, cylindric-elliptic, smooth, inamyloid, colorless, (Breitenbach), 14-16 x 4.5-5.5 um (Berthier). REMARKS Macrotyphula juncea does not produce sclerotia and has smaller spores. Typhula erythropus is found in similar habitats but is shorter with a distinct club and is white rather than honey-yellow. Typhula incarnata has a more distinct head and a pinkish fruitbody.

506b	Not with these characters	507

507a	Dark brown, purplish brown or black fruitbody, (spores colorless under microscope, 20-44 x 4-6 um, one-celled)	Microglossum atropurpureum

1-7 cm high, club-shaped, compressed (flattened somewhat); spore-bearing portion 0.2-1.5 cm wide, 1/3 to 1/2 the length, dark brown, purplish black or black, stem 0.2-0.8 cm wide, round in cross-section, brownish black or black, smooth or minutely scaly. FRUITING on soil. MICROSTRUCTURES ascospores (16)20-44(52) x 4-6 um, nearly cylindric, or allantoid (curved sausage-shaped), one-celled, paraphyses not or slightly projecting beyond the asci, straight or slightly curved above, colorless, not or slightly enlarged at the tips. REMARKS Microglossum fumosum has yellowish brown to umber fruitbody. Microglossum olivaceum has predominantly brown to olivaceous fruitbody and spores mostly less than 20 um long. Geoglossum species have brown spores under microscope (G. fallax may have many colorless spores, but is brown in color), and generally spores multiseptate as well as longer. Trichoglossum hirsutum and T. velutipes have setae (bristles). Mains (1955) includes here under Microglossum atropurpureum three species of Durand that are treated as separate species of Corynetes by Seaver (1951). According to Mains, Durand separates Corynetes purpurascens from C. atropurpureus on the basis of having a more distinctly purplish tint when fresh and more abruptly thickened tips to the paraphyses, and Durand separates C. robustus from C. atropurpureus on the basis of lack of an epithecium and paraphyses slightly thickened and curved at the tips. With regard to another close species Seaver (1951) gives the paraphyses of Corynetes arenarius as conspicuously brown, as opposed to colorless or only slightly purple-tinted at tips for the other three. According to Alan Silverside at the University of Paisley, they have in Britain the same 4 species as given by Seaver under Corynetes, but the names will need to be different. It is not clear which of the members of the Microglossum atropurpureum complex are found in the Pacific Northwest. Breitenbach gives Corynetes atropurpureus (Batsch ex Fr.) Durand as synonym of Thuemenidium atropurpureum (Batsch) Kuntze. The description here is derived from Mains (1955). 

507b	Not with these characters	508

508a	Black fruitbody, (spores brown under microscope, (45)55-78(90) x 6-8 um; paraphyses straight or somewhat curved in upper part, closely septate in upper part where the cells may be enlarged with constrictions at the septa)

1.5-10 cm high, club-shaped, black; spore-bearing upper part 0.3-0.8 cm wide, 1/3 to 1/2 of the length of the fruitbody, flattened, stem 0.1-0.4 cm thick, round in cross-section, smooth. FRUITING scattered to crowded, on soil or also in Sphagnum or other mosses MICROSTRUCTURES ascospores (45)55-78(90) x 6-8 um, straight or somewhat curved, dark brown, mostly 7-septate in type variety, but variably septate in another variety, asci 8-spored, 150-190 x 20 um, clavate; paraphyses exceeding asci, straight or somewhat curved above, colorless or light brown in lower part, light to dark brown and closely septate in upper part, the upper cells various enlarged in different varieties and more or less constricted at the septa. REMARKS This is the Mains (1954) concept. There is considerable confusion about this name. Geoglossum fallax is brown, rarely black, and has different paraphyses. Geoglossum simile of eastern North America is separated by its paraphyses which are "closely and abundantly septate above, with the upper cells not or slightly enlarged, constricted at septa to form many oblong, ellipsoid or obovoid 2-celled segments" (Mains 1954).

508b	Dark brown to black fruitbody, (spores brown under microscope, 30-90 x 4.5-6.5 um, paraphyses that are straight or strongly curved in upper part, sparsely or moderately septate, not constricted at septa, the paraphyses not closely septate in upper part, ( = G. nigritum (Pers.) Cooke)	Geoglossum umbratile

up to 7 cm high, variable in size, club-shaped, spore-bearing upper part 0.1-0.5 cm wide, 1/3 or 1/2 the length of the fruitbody, somewhat flattened, dark brown to black, stem 0.05-0.2 cm wide, slender, round in cross-section, dark brown to black, sometimes somewhat viscid, bald, minutely downy or with fine particles or fine scales. FRUITING scattered or in small groups, type variety very variable in habitats, occurring among Sphagnum and other mosses, on soil in well drained areas and on wet soil by streams and in bogs, var. heterosporum on a conifer log. MICROSTRUCTURES ascospores (40)60-78(90) x 4.5-6.5 um, straight or somewhat curved, dark brown; asci mostly 8-spored, rarely less (except in variety heterosporum described from Michigan which also has somewhat shorter spores); paraphyses colorless to brown, longer than asci, "straight or strongly curved above, cylindric, not or slightly enlarged at apex, the terminal cell cylindric, narrowly obovoid or clavate," (Mains 1954). REMARKS Geoglossum simile (of eastern North America) and G. glabrum, “differ in having paraphyses that are closely septate above with the cells variously enlarged and more or less constricted at the septa”, (Mains 1954). Geoglossum fallax is brown, rarely black, and has different paraphyses. The name Geoglossum nigritum is considered to have been misapplied.

706a	Head reticulate (like a network on the surface with pits between ridges); outer covering may be pale pinkish or pale purplish or whitish; relatively common, fruiting in a variety of habitats	Phallus impudicus

develops from egg-like structure just underground, 4-6 cm x 3-5 cm, spherical or elongated, the outer covering pinkish or purple or whitish, rupturing as stem elongates over 1 or 2 hours, forming a roughly cylindric fruitbody up to 25 cm tall, head 1.5-4 cm across, with whitish, reticulate (pitted and ridged) surface that becomes coated with olive to olive brown slime, the slime foul-smelling when fruitbody mature, a hole at the top sometimes covered by a fragment from outer covering, stem up to 3 cm wide, equal or widest in middle, hollow, surface sponge-like, white or lower part pinkish, volva at stem base is pale pinkish or pale purple or whitish, also a thin veil not extending appreciably below margin of fertile head. FRUITING in groups or clusters in grass, sandy or cultivated soil, on compost, under trees or shrubs; spring to late fall. MICROSTRUCTURES basidiospores 3-5 x 1.5-2.5 um, elliptic or oblong, smooth. 

706b	Head covered with intricate network of gill-like plates and tubercular (bump-like) processes; outer covering whitish but discoloring brownish where handled; rare, fruiting in sandy soil	Itajahya rosea

begins as an underground egg-like form that is spherical to obovoid, 2.5-8 cm in diameter, discoloring brownish where handled; the fruitbody ruptures from the egg, extending itself in about 6 hours, the cap in the form of a cylindric hood attached by its upper edge at the prominent collar at the top of the stem, and initially covering the opening at the stem’s upper end, the hood covered on the outside with an intricate network of gill-like plates and tubercular (bump-like) processes between which the spore mass is conspicuous, olivaceous, mucilaginous, and foul-smelling, the lower margin of the hood free but initially covered by the spore mass; eventually the cap curves upward and falls to the ground, revealing the funnel-shaped entrance to the top of the stem with its very prominent collar; stem 6.5-17 cm long and 2.5-4.5 cm wide below the cap, cylindric or widening downward, spongy, hollow, may be white or pink, volva at base. FRUITING in sandy places. MICROSTRUCTURES basidiospores 3-4 x 2-2.5 um, broadly ovoid or elliptic, smooth. REMARKS rare, but recorded from WA (L. Norvell, pers. comm.)
