The following species have been added to the key: Ossicaulis lignatilis, Pleurotus pulmonarius, Pleurotus populinus, Panellus longinquus, Resupinatus striatulus, and Hohenbuehelia nigra. Hypsizygus tessellatus replaces Pleurotus elongatipes, and Pleurotus candidissimus is renamed Cheimonophyllum candidissimum. Pleurotus sapidus and Pleurotus ulmarius were deleted. The structure of the key was not altered except to accommodate these changes. I am grateful to Scott Redhead, and to Jim Ginns, Lorelei Norvell, and other members of Pacific Northwest Key Council, for help in clarifying species concepts. In 2008, Tectella patellaris was added.
Two other Hohenbuehelia species are mentioned in notes, and a few proposed name changes are discussed. An additional Hohenbuehelia does not fit easily into the existing key and is rare in the Pacific Northwest. Hohenbuehelia mastrucata has a gray to buff cap up to 6 cm across, covered with blunt spines on a thin skin that covers a gelatinous layer, has white to beige gills, and is laterally attached on decayed hardwood without a distinct stem.
All Pleurotoid mushrooms are gilled fungi and are lignicolous. Species vary in size from minute to large. Stems are generally eccentric (off-center) or lateral, plug-like or absent. Spores are roundish to elliptical and have smooth thin walls. Spores of Cheimonophyllum, Hohenbuehelia, Ossicaulis, Pleurocybella, Pleurotus, Panus, Phyllotopsis, and Resupinatus are non-amyloid; spores of Panellus are amyloid. Spore deposit is most often white but Phyllotopsis nidulans has light cinnamon reddish or pinkish spores, Panellus longinquus has dingy yellow-cream spores, Hypsizygus tessellatus has buff spores, Panellus serotinus has yellow spores and species in the Pleurotus ostreatus complex may have spores that are lilac-tinged. Crepidotus species, which are common and look somewhat similar, but are not considered Pleurotoid species, have brown spores and are not included.
Sometimes species may grow in solitary fashion, but it is more common to find many fruiting bodies to be observed at one time. Some species are gregarious, some clustered, and some shelving. Both conifer and hardwood areas provide habitat.
Regarding edibility, no poisonous species are known, but some are too minute, or too tough, or not desirable because of styptic, sour, or bitter flesh. (It must be noted that two members of Spokane Mushroom Club have reported nausea and stomach upset from eating Panellus serotinus.) Edible and choice species will be noted in individual descriptions.
In the following key, stem attachment is described as "eccentric" when stem is off-center; "lateral" is used when attachment to host is at edge of cap; "plug" describes a tough lateral attachment no longer than 2 cm.
Information and material has been gathered from many sources but special acknowledgement must be given to the publications of Dr. A. H. Smith and Dr. Orson Miller. Appreciation is expressed to Kit Scates for specimens, slides, assistance and advice.

5a (2b) Cap usually less than 1 cm broad, chocolate brown to black; if buff then usually less than 0.5 cm broad
................................................................................Resupinatus applicatus
CAP 0.7-1.5 (2.0) cm; fanshaped to shell-shaped; chocolate brown to black when wet, not striate or translucent striate, ash-gray and non-striate when dry; basal 1/3 to 2/3 covered with shaggy stiff coarse tomentum, especially dense over pseudostem, margin bald to pruinose; flesh gelatinous and black in mass. GILLS decurrent and radiating from pseudostem, moderately narrow and close; dark brown when revived, edges whitish; edges entire. STEM lateral pseudostem, 0.2-0.5 cm broad. HABITAT occurs most commonly on bark of hardwood logs such as oak and maple, or on hard rinds formed on hardwood logs by fungi such as Ustulina deusta. MICROSTRUCTURES spores (4.0)4.4-6.0 x 4.0-4.8 um, round or nearly round, smooth, inamyloid. REMARKS Many of the descriptions of Resupinatus applicatus confuse it with Resupinatus striatulus which occurs at least in BC, but is very small (0.15-0.7 cm but averages 5-10 times smaller than R. applicatus). It is cupshaped rather than fanshaped, dorsally or laterally attached; beige, pinkish brown, gray-brown, to blackish, darkening on drying, sometimes has striate or sulcate margin, has gills that are cap-colored or paler and radiate from the point of attachment, and grows on undersides of old and well-rotted conifer or deciduous wood that is without bark and is usually soft and white-rotted. Spores are (3.3)4.0-6.0 x (3.1)3.5-5.0 um, round or nearly round, inamyloid, and colorless. Resupinatus species have a distinctive cell surface structure. This account of the Resupinatus species is derived from Thorn whose specimens of Resupinatus applicatus were eastern in North America. Some authors regard the two as synonyms. Three Hohenbuehelia species will key out here. 1) Hohenbuehelia nigra (Schw.) Singer has been recorded from Oregon, Montana, and Yukon Territory. Dark, cup-shaped to shell-shaped fruitbodies are up to 0.8cm across and dorsally attached without a stem or with a short pseudostem. Gills are markedly spiny under 10x from metuloids. They grow on dead deciduous wood of Juglans (walnut) and Alnus (alder). Spores measuring mostly 7.5-10 x 3.5-4.5 um are smooth and inamyloid, and there are lanceolate metuloid pleurocystidia 33-75 x 8-12(14) um, as well as smaller fusoid-clavate cystidia with a drawn-out neck. 2) Hohenbuehelia unguicularis is the label for two collections at the Pacific Forestry Centre (from British Columbia and Yukon Territory). It can be recognized by its dark cup-shaped to fan-shaped fruitbodies up to 0.6cm across with pale tomentum near the apex which may be drawn out into a pseudostem, and by its gills that are silvery or pale tan when young and become dark when old. It fruits on hardwood, usually in late fall through spring. Smooth inamyloid spores are mostly 6.0-8.5 x 3.0-4.0 um, and metuloids are scarcely projecting. 3) Hohenbuehelia cyphelliformis is the label for several collections from British Columbia at the University of BC. The cup-shaped, pendent, or shell-shaped fruitbodies are grayish brown to blackish, up to 0.6cm across, and gills are distant and strikingly white. They are dorsally or laterally attached without a stem to dead twigs of dicotyledonous plants or on their stems. Spores are mostly 8-10 x 2.8-3.8 um, and metuloid cystidia to not project above the hymenial surface.
5b Cap usually more than 1 cm broad, ochraceous to buff or dull brown or purplish
................................................................................6

GILLS radiating from point of attachment, fairly well spaced; fawn to pink, fading in age to reddish brown when dried. STEM absent. HABIT and HABITAT birch sticks and limbs on ground; usually several to gregarious; sometimes nearly imbricate; fruiting in late summer and fall; sometimes collected in winter. DISTRIBUTION O.K. Miller examined material from ID, and D. Lowe reported it from BC, but records are sparse. EDIBILITY unknown. SPORE PRINT white. MICROSTRUCTURES spores (4.0) 5.0-7.0 x 1.2-2.0 um, oblong to sausage-shaped, amyloid. REMARKS "ringens" means "wide open", from Latin.
6b Cap ochraceous to light buff or dull brown
................................................................................7
7a Partial veil not present, taste unpleasant, stem short
................................................................................Panellus stipticus
7b Partial veil covers gills when young, leaving hanging remnants on margin, taste mild, stem usually absent
................................................................................Tectella patellaris
CAP 0.7-2.0cm across, circular, with concave to flattened gill-bearing surface facing downward, attached at its edge or upper surface, margin inrolled; ocher to dingy brown; slimy to viscid when young, becoming dry and fibrous to floccose-scaly, margin decorated with hanging pieces of veil tissue; flesh tough, ocher. ODOR and TASTE not distinctive. GILLS close to distant, narrow; pale brownish; pale buff partial veil covering gills when young. STEM usually absent, if present then very small. HABIT and HABITAT in groups or clusters on logs and fallen branches of hardwoods, various times of year, uncommon. EDIBILITY unknown. SPORE PRINT white. MICROSTRUCTURES spores 3-5 x 1-1.5 microns, cylindric or curved cylindric, smooth, weakly amyloid. REMARKS The partial veil in a stemless agaric is very unusual.

................................................................................14
14a Cap becoming marbled with watery spots, (spores 4-5(6) x 4-4.5 um, round to nearly round)
................................................................................Hypsizygus tessellatus
(Hypsizygus elongatipes (Peck) Bigelow and Hypsizygus marmoreus (Peck) Bigelow are synonyms; Hypsizygus ulmarius (Bull.: Fr.) Redhead is not a synonym.)
CAP 2-14 cm broad, convex, nearly flat at maturity; pinkish cream with distinctive darker, round water spots over the center; moist, smooth without hairs; flesh firm but not tough, white to pinkish buff. GILLS adnexed (notched), with a thin line on the upper stem, subdistant, broad, veined, buff to pinkish buff. STEM 4-22 x 0.4-2.0 cm, equal or gradually tapering toward base, often curved or bent, white, smooth except near to top where there is white down, and the base, which has white stiff hairs; veil absent. HABIT usually several stalks from a common base. HABITAT on poplar or occasionally other hardwoods. EDIBILITY edible. SPORE PRINT buff. MICROSTRUCTURES spores 4-5(6) x 4-4.5 um, round to nearly round, smooth. REMARKS The description above is derived from Miller's description of Pleurotus elongatipes, except the habitat and microstructures which are from Redhead. Much confusion has surrounded this species. Arora, Lincoff, Bessette, and Barron all give Pleurotus ulmarius as a synonym of this species. Scott Redhead says that Hypsizygus tessellatus (Bull. ex Fr.) Singer is a species that often grows caespitosely, in North America on poplar and Sugar Maple, occasionally on Betula, Ulmus, Abies, and Fagus, has a guttate-marmorate cap when fresh, (Bulliard's 'tessellatus' emphasizes the spots, Peck's 'marmoreus' the lines between, but cap not cracked in a tessellated manner), and has small round to nearly round spores 4-5(6) x 4-5 um, but H. ulmarius (Bull.:Fr.) Redhead in contrast usually grows solitarily, in North America frequently on elm and box elder (Acer negundo), occasionally on Populus and other Acer species, has a smooth not guttate cap when fresh which often becomes areolate-cracked with age and has larger nearly round to broadly elliptic spores (5)5.5-6(7) x 5-5.5(6) um; both species are found in Eurasia, the latter is found in North America in areas east of the continental divide and generally central latitudes, H. tessellatus (Bull. ex Fr.) Singer is found is found from coast to coast and north to the Yukon. It is spelled H. tessulatus by most authorities.
14b Cap not becoming marbled with watery spots, (spores 4-6 x 3.0-3.5 um, elliptic to broadly elliptic)
................................................................................Ossicaulis lignatilis
(previously known as Pleurotus lignatilis)
CAP 5-12 cm or even larger, convex to cushion-shaped, becoming flat to shallowly depressed, with inrolled to incurved edges, often becoming indented or incised, often chalky-white, with or without faint rose to pale vinaceous tints on disc, may be grayish initially, or become somewhat grayish or gray-brownish or yellow-brownish; dry, opaque, may be downy-floury; flesh tough, fleshy, with conspicuous membranous layers. ODOR fungal, sometimes fleetingly farinaceous when first cut. TASTE not distinctive to strongly fungal. GILLS adnate to adnexed or decurrent by short tooth, crowded to subcrowded, moderately narrow (up to 0.6 cm broad); white but drying yellowish white, when old sometimes yellowing, browning; with even or eroded edges. STEM 1-6 x 0.15-1 cm, sometimes longer or thicker, often short and strongly curved, usually swollen in lower part, usually off-center, sometimes more or less central, often with immature fruiting bodies close by; colored like cap, occasionally with faint vinaceous-rose tint; with a surface similar to cap, often slightly more matted-roughened at top, otherwise like suede, white mycelial strands often noted near base. HABITAT on living or dead hardwood or sometimes conifer trunks. EDIBILITY reported in Europe to be edible. SPORE PRINT white. MICROSTRUCTURES spores 4-6 x 3.0-3.5 um, elliptic to broadly elliptic, smooth, inamyloid; coralloid hyphae in the cap cuticle, mucilaginous coating on hyphae of stem.
15a (11a) Cap quite densely hairy
................................................................................16
15b Cap minutely hairy or glabrous (bald)
................................................................................17

(also known as Sarcomyxa serotina (Schrad.: Fr.) Karst.)
17b Cap not colored as above
................................................................................18
18a Cap pristine white and transparent looking; flesh extremely thin
................................................................................Pleurocybella porrigens
(also known as Nothopanus porrigens (Pers.) Singer, Pleurotus porrigens (Pers. ex Fr.) Kuehner & Romagnesi, Pleurotellus porrigens (Pers. ex Fr.) Kummer, and Phyllotus porrigens (Pers. ex Fr.) P. Karst.)
18b Cap tannish, brownish
................................................................................19
19a Cap brown, wedge-shaped (shoehorn-shaped), feels lubricous (soapy)
................................................................................Hohenbuehelia petaloides (See 9a.)
19b Cap ash-gray, tannish, (if brown, not as above), no gelatinous layer or touch
(Pleurotus ostreatus complex)
This complex is difficult to separate except by mating studies: while the following characters may lead to one member's being more probable than another, collections will usually be best identified as Pleurotus ostreatus complex. Vilgalys et al. (1993) established the presence of Pleurotus populinus and P. pulmonarius in the Pacific Northwest. Pleurotus ostreatus is recorded from the Pacific Northwest prior to the 1993 differentiation including collections from alder described as up to 20 cm across, with lilac spores, (Bandoni & Szczawinski 1964).
