This member of the genus Mycena features fairly robust size for a Mycena, with caps 20-30mm on average, which is several times the size of the dainty and smallest Mycenas. It is a saprobe, feeding on woody debris litter and is commonest in late fall and winter. The caps are gray to brownish gray and may fade to an ashen color. They are prominently striate, conical with teh disc often lighter in color. The gills are close, attached broadly to the stem and of a lighter gray color with a white margin. They drop a white spore print. The stalks are up to 13cm long, equal, grayish, and fairly fragile. There is no odor and they are too small for food fare. They can often be found on cold winter days when no other fungi are up.
