He also described a variety Mycena alnicola var. odora with an odor and taste raphanoid.[2]

Description

The cap is 1–2.5 cm wide. At first campanulate-obtuse, to convex at maturity. The pileus has a pale blue luster in younger specimens; the cap is hygrophanous. The cap disk is dark brown, and the rest of the cap is light brown (or beige), the margin usually whitish. The pileus margin is furrowed-striated.

The gills are adnate, interveined, and narrow to moderately broad. The gill color is gray and has entire ridges. The stem is 4–6 cm long × 1.5–2 mm wide, equal, hollow; covered with a dense white bloom in the stipe apex. The stipe color is dark beige to dark mouse gray, cap-colored at maturity. Smell and flavor is sweet.

Basidia with four sterigmata, basidiospores ellipsoid, smooth, amyloid, (6) 7–9 (10) × 4–5 μm. Cheilocystidia present, clavate to broadly fusiform; subcylindrical to spindle-shaped or sometimes with one or two protuberances; smooth or with low incrustation at apex in KOH. Cheilocystidia size range: 26–40 × 8–17 μm. Pleurocystida are rare.[3]
