Fuzzy Foot
Mycena overholtsii
''Mycena overholtsii'', commonly known as the snowbank fairy helmet or fuzzy foot, is a species of fungus in the family Mycenaceae. The mushrooms produced by the fungus are relatively large for the genus ''Mycena'', with convex grayish caps up to 5 cm in diameter and stems up to 15 cm long. The gills on the underside of the cap are whitish to pale gray, and initially closely spaced before becoming well-spaced at maturity after the cap enlarges. The mushrooms are characterized by the dense covering of white "hairs" on the base of the stem. ''M. overholtsii'' is an example of a snowbank fungus, growing on well-decayed conifer logs near snowbanks, during or just after snowmelt. Formerly known only from high-elevation areas of western North America, particularly the Rocky Mountain and Cascade regions, it was reported for the first time in Japan in 2010. The edibility of the mushroom is unknown. ''M. overholtsii'' can be distinguished from other comparable species by differences in location, or spore size.
