Summary:
Features include a silky whitish cap with an umbo or papilla, crowded gills with whitish-fringed edges that bruise reddish-tinged, a whitish stem that is equal to slightly bulbous at the base and pruinose in the upper sixth, and microscopic characters. The description is derived from Kuyper(1). Kuyper has considered it a form of Inocybe whitei.
Inocybe armeniaca occurs at least in WA (P. Brandon Matheny, pers. comm.). There are two collections by O. Ceska from BC at the University of British Columbia. It also occurs in Denmark, Netherlands, (Kuyper)
Gills:
narrowly adnate, moderately crowded, 25-40 reaching stem, 1-3 subgills between neighboring gills, gills 0.3-0.5cm broad, not ventricose to subventricose; grayish isabella to grayish brown or yellowish brown, sometimes with pinkish stains; edge fimbriate [fringed] to subflocculose [somewhat flocculose], "whitish, on bruising with reddish tinges"
Stem:
1.8-5.7cm x 0.15-0.5cm, equal or almost equal to slightly bulbous but not marginate; solid; whitish, slowly discoloring to ochraceous orange, similar to cap color; pruinose to slightly hairy in top 1/6, longitudinally subfibrillose [somewhat fibrillose] below
Veil:
cortina present in young specimens, leaving no remnant on stem; sometimes somewhat dentate or somewhat appendiculate at margin
Odor:
spermatic
Microscopic spores:
spores (7.0)7.5-9.5(10.0) x 4.5-6.0 microns, on average 8.1-8.9 x 4.9-5.3 microns, regular to somewhat almond-shaped; basidia 4-spored, 23-32 x 7-9 microns; pleurocystidia frequent, 43-65(70) x (12)14-22 microns, "fusiform to subutriform, thick-walled", wall to 1.5-2 microns, colorless or (very) pale yellow, with crystals on apex, cheilocystidia frequent and similar to pleurocystidia, paracystidia frequent, (broadly) clavate, thin-walled, colorless
