Microglossum atropurpureum


Microglossum atropurpureum is a species of fungus in the family Leotiaceae. In the UK, it has been given the recommended English name of dark-purple earthtongue. Ascocarps (fruit bodies) 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.[2]

Microglossum atropurpureum is found in eastern North America and Europe, where it is typical of waxcap grasslands, a declining habitat due to changing agricultural practices. As a result, the species is of global conservation concern and is listed as "vulnerable" on the IUCN Red List of Threatened Species.[1]
