E-Flora BC: Electronic Atlas of the Flora of British Columbia

Summary:
Features include 1) a convex to funnel-shaped, hygrophanous, gray to gray brown cap, 2) decurrent, gray to gray brown gills, 3) a stem colored as the moist cap beneath a grayish to whitish fibrillose coating, 4) farinaceous odor and taste, 5) habitat under trees, 6) white spore deposit, and 7) narrow spores.

Bigelow(5) cites specimens only from northeastern North America, (MA, ME, NY, VT), but there are collections from WA and OR at the University of Washington. O. Ceska deposited a collection from BC at the University of British Columbia. Schalkwijk-Barendsen reported it for Edmonton AB (although the odor is different).

Gills:
short-decurrent to long-decurrent (often evenly and forming a collar on stem top), close, narrow to moderately broad (0.2-0.5cm), occasionally forked or anastomosed, rather soft; gray, tinged brownish when old but very slow to fade in contrast with cap; not interveined, (Bigelow), decurrent, relatively distant; "dirty white to pale brown with eroded edges", (Schalkwijk-Barendsen), decurrent; grayish (Courtecuisse)

Stem:
2-6.5(8)cm x 0.3-0.6(0.8)cm at top, "equal or the base enlarged and tapering upward", stuffed soon hollow; colored as moist cap beneath grayish to whitish fibrillose coating; fibrillose coating gradually becoming appressed, "base with watery buff or whitish tomentum and adhering to adjacent leaves or needles", (Bigelow), up to 4cm long and up to 0.7cm wide, whitish streaked with brown; white erect hairs at stem base (cystidia), (Schalkwijk-Barendsen), up to 7cm long and up to 0.5cm wide, colored as cap, bald, (Courtecuisse)

Veil:
[presumably absent]

Odor:
farinaceous (Bigelow), aromatic, of sweet scented bedstraw (Schalkwijk-Barendsen), mealy (Courtecuisse)

Taste:
farinaceous (Bigelow)

Microscopic spores:
spores 5.5-7(8) x 3-3.5 microns, elliptic to elliptic oblong, smooth, inamyloid; basidia mostly 4-spored, 15.5-27 x 4-6 microns; [pleurocystidia and cheilocystidia presumably absent]; clamp connections present, (Bigelow), spores 6.5-8 x 3.5-4.5 microns, (Moser)

Spore deposit:
white (Bigelow, Schalkwijk-Barendsen)
