Overview

Dermoloma cuneifolium is a species of fungus in the family Tricholomataceae, and the type species of the genus Dermoloma. Originally named Agaricus cuneifolius by Elias Magnus Fries in 1818, it was transferred to Dermoloma by Marcel Bon in 1986.

Dermoloma cuneifolium faces significant threats from habitat degradation and loss of old-growth forest ecosystems where it depends on specific soil conditions and mycorrhizal relationships. Climate change and altered precipitation patterns are disrupting the delicate moisture balance required for fruiting body development and spore dispersal. The species' limited distribution and specialized ecological requirements make it particularly vulnerable to environmental changes.

Threat summary

Habitat

Inhabits mature coniferous and mixed forests, particularly in areas with well-developed organic soil layers and stable moisture conditions. Typically found in association with specific tree species where it forms mycorrhizal relationships, often in undisturbed forest floor environments with rich humus layers.
