Cortinarius dalecarlicus

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Cortinarius dalecarlicus faces significant pressure from forest management practices that alter the composition and structure of its preferred old-growth coniferous habitats. The species' dependence on specific mycorrhizal relationships with mature trees makes it particularly vulnerable to logging activities and forest fragmentation. Climate change poses an additional threat by potentially shifting the suitable temperature and moisture conditions required for fruiting body development and spore dispersal.

Threat summary

Habitat

This fungus occurs in mature coniferous forests, particularly those dominated by spruce and pine species in northern European regions. It forms mycorrhizal associations with tree roots and typically fruits in mossy, acidic soils of old-growth forest understories.
