Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The Gassy Webcap faces significant pressure from habitat degradation as its specialized coniferous forest ecosystems experience fragmentation and altered soil chemistry. Climate change poses an additional threat by shifting temperature and moisture regimes that this mycorrhizal species depends on for successful fruiting and spore dispersal. The fungus's narrow ecological requirements and dependence on specific host tree relationships make it particularly vulnerable to forest management practices that alter understory conditions.
Habitat
Cortinarius traganus inhabits mature coniferous forests, particularly those dominated by spruce and pine, where it forms essential mycorrhizal partnerships with tree roots. The species typically fruits in acidic, well-drained soils with rich organic matter layers characteristic of old-growth forest floors.
