Biology

provided by Arkive
The earth tongue fruiting bodies of this species are produced between August and December (2). This fungus obtains its nutrients from the soil (2). Fungi are an enormous group of organisms that are so distinctive from both plants and animals that they are placed in their own kingdom. The main body of the fungus is composed of a multitude of microscopic threads (known as 'hyphae') which are located within the substrate (5). The fruiting body (such as the more familiar mushroom or toadstool) is produced to release spores and thus allows reproduction to occur. Fungi feed by absorbing nutrients from their surroundings.

Description

provided by Arkive
Earth tongues are highly distinctive fungi; the ridged and leathery fruiting body above the stem does indeed resemble a tongue. In this species, the head of the fungus is reddish-brown or purplish-black in colour, and it is not separated from the non-fertile stem (or ¿stipe¿) (2).

Microglossum atropurpureum

provided by wikipedia EN

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]
