Gills white, widely spaced, usually branching and curving, attached to stalk. Stalk usually white at top shading to gray or black at base. Fruits in summer.

An elegant little decomposer of forest debris, found worldwide.

Easily overlooked, but, if found, easily identified by its small size, growth on wood, wide-spaced gills and two-toned stalk. The related Pinwheel (Marasmius rotula) is even smaller, with a very thin, black, wiry stalk
