A number of Gymnopus species form clusters with stipes fused together at their bases, making it possible to excavate the entire unit from the substrate. Gymnopus acervatus has caps that are reddish brown with paler edges, narrow, pale pinkish gills, and red to red brown, hollow, shiny stipes with whitish hairs and narrow strands at the base. It is a common inhabitant of conifer forest, occurring on rotting logs and stumps, and other woody debris.
