Distribution: M. overholtsii apparently is restricted to the mountains of western North America. M. overholtsii appears in the mountains in late spring to early summer on wet rotting stumps and logs recently exposed by, or still partially covered with, melting snow.

Spores: spores measure 5--8 x 3.5--4 µm, and the sometimes hard-to-see cheilocystidia are smooth, slender, and cylindrical or sometimes a bit club-shaped

Conservation Status: Not of concern

Description:
Identification Notes:

Mycena overholtsii is a large brown species (“a most un-Mycena-like member of the genus” according to the late Dutch mycologist, R.A. Maas Geesteranus) that grows in clusters on wood, in much the same manner that M. maculata and M. galericulata do. Also, compared to the other two species, the gills are more distinctly gray and the lower portions of the stipes are densely covered with long white hairs The spores measure 5--8 x 3.5--4 µm, and the sometimes hard-to-see cheilocystidia are smooth, slender, and cylindrical or sometimes a bit club-shaped
