Summary:
Features include 1) small size, 2) a chalky white, convex, centrally depressed, striate, micaceous cap that develops a grayish cast, 3) pliant white flesh, 4) decurrent white gills with micaceous edges, 5) a white stem that is cartilaginous and pruinose, 6) growth on conifer debris, 7) presumably a whitish spore deposit, and 8) cylindric, smooth, amyloid spores. The description is derived from Redhead(17).
Resinomycena montana has been found in BC and WA, (Redhead(17)).
Cap:
0.35-0.55cm across, "convex and slightly depressed centrally, vaguely striate to chalky white", developing grayish cast when dry; micaceous [like flecks of mica], obscurely corrugated-striate
Flesh:
pliant; white
Gills:
arcuate decurrent, moderately spaced, 2 tiers of subgills; white; with micaceous edges
Stem:
0.9-2.3cm x 0.04-0.06cm, equal, cartilaginous or tougher; white; "finely powdered overall"
Odor:
not distinctive
Microscopic spores:
spores 8-9.3 x 2.8-4.5 microns, cylindric to narrowly elliptic, smooth, amyloid, with prominent apiculus; basidia 4-spored, 20-21 x 6.8-7.2 microns, clavate subcapitate, with clamp connection; cheilocystidia "abundant, forming a sterile edge", 42-52 x 6-6.2 microns, narrowly clavate to cylindric and slightly strangulate, "occasionally with a short apical elongation, with scant to abundant resin exudates"; cap epicutis "a suberect to tangled turf of polymorphic cystidia", 45-67 x 2.5-7 microns, "varying from a majority of elongated clavate oleocystidia to filiform or dendroid nonresinous elements"; caulocystidia similar to pileocystidia; clamp connections mentioned for basidia, cap trama, and stem hyphae
Spore deposit:
[presumably white or whitish]
