It is known from BC and WA, (Niskanen(3)). The type is from WA. Harrower(1) #145 is from BC.
Cap: 2-4cm across, hemispheric becoming low convex to almost flat with low broad umbo; strongly hygrophanous, reddish brown with center dark reddish brown; dry, matte, edge whitish-fibrillose
Flesh: in cap dark reddish brown, in stem pale brown
Gills: adnexed to emarginate, moderately broad, moderately thick, medium spaced; "at first pale brown, later dark brown"; edge whitish
Stem: 5-7cm x 0.3-0.5cm at top, 0.5-0.8cm wide at base, "slightly clavate to clavate"; whitish silky-fibrillose, when old or when handled the fibrillosity lost and the stem colored more like the stem flesh; basal mycelium white at first
Veil: universal veil white and fairly sparse
Odor: indistinct
Microscopic spores: spores 7.5-8.5(9.0) x 5.0-6.0 microns, "amygdaloid to broadly amygdaloid, moderately verrucose, somewhat more strongly ornamented at the apex, moderately to fairly strongly dextrinoid"; basidia 4-spored, 25-32 x 7-8.5 microns, clavate, "with yellow to yellow brown granulose contents" in Melzer''s reagent; gill trama hyphae smooth in Melzer''s reagent; clamp connections present
