Pholiota squarrosa
https://www.mushroomexpert.com/Pholiota_squarrosa.html
Ecology: Saprobic and possibly parasitic; growing in clusters on the wood of hardwoods or conifers; often found at the bases of living or dead trees; especially common on aspens and spruces in the Rocky Mountains; summer and fall; fairly widely distributed in North America.
Cap: 3-12 cm; convex, becoming broadly convex or broadly bell-shaped; dry; yellowish underneath conspicuous buff to tawny scales.
Gills: Attached to the stem or beginning to run down it; close or crowded; whitish to yellowish when young, becoming greenish yellow and eventually rusty brown; at first covered by a partial veil.
Stem: 4-12 cm long; up to 1.5 cm thick; dry; with an ephemeral ring or ring zone; yellowish, sometimes becoming brown to reddish brown from the base up; covered with conspicuous buff to tawny scales.
Flesh: Whitish to yellowish.
Odor and Taste: Odor not distinctive or strongly of garlic; taste mild or somewhat unpleasant. The odor of my collections in Colorado is quite strong and quite distinctive--like a cross between garlic and lemon.
Chemical Reactions: KOH negative on cap surface.
Spore Print: Cinnamon brown.
Microscopic Features: Spores 6-8 x 4-5 ; smooth; more or less elliptical; with an apical pore; reddish brown in KOH. Pleurocystidia clavate to clavate-mucronate or subfusiform; some with refractive contents in KOH; to 45 x 14 . Cheilocystidia subfusiform to fusoid-ventricose or clavate; to 43 x 15 . Pileipellis an interwoven layer of cylindric hyphae with clavate to fusoid-ventricose terminal elements. Clamp connections present.
