Dark-purple Earthtongue

"Microglossum atropurpureum" is a species of fungus in the family Leotiaceae. Ascocarps are black, often with a purple tint, and are irregularly club-shaped. They occur in soil and resemble earth tongues, but are microscopically distinct. The species was formerly referred to the genus "Geoglossum", but is not closely related to the Geoglossomycetes.
