Spores: September to October
Conservation Status: Not of concern
Baeospora myosura (Fries) Singer also occurs on spruce (mostly) and Douglas-fir cones, but has has a brownish cap often with a pale edge that fades to pale tan, even more crowded buff gills, light brown, somewhat hairy stipe with whitish strands on the base, smaller (3--4.5 x 2--3 µm) weakly amyloid spores, clamp connections, and cap cuticle with mostly thin, flat-lying, hyphae. S. albipilatus (Peck) V.L. Wells & Kempton is a litter-inhabiting species that grows in scattered groups, usually at high elevation, often in the spring near melting snow. Despite its species epithet (Latin for white cap), the cap color usually is some shade of medium to dark brown.
