Cortinarius multiformium
Local name: Vielgestaltiger Klumpfuß
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Cortinarius multiformium faces severe decline due to the destruction and fragmentation of old-growth coniferous forests across its European range. Intensive forestry practices that favor monoculture plantations over diverse, mature forest ecosystems have eliminated critical mycorrhizal partnerships with ancient tree hosts. Atmospheric nitrogen deposition from industrial sources alters soil chemistry, disrupting the delicate nutrient balance required for this specialized fungus to fruit and reproduce.
Habitat
This rare cortinarius species inhabits mature coniferous forests, particularly those dominated by spruce and fir trees in montane regions of central Europe. It forms essential mycorrhizal associations with old-growth conifers, requiring undisturbed forest floors with deep organic matter accumulation.
