Mealy Bigfoot Webcap
Cortinarius caerulescens
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The Mealy Bigfoot Webcap faces severe pressure from habitat degradation as old-growth coniferous forests are cleared for timber harvesting and urban development. Climate change poses an additional threat by altering the specific soil chemistry and moisture conditions this mycorrhizal species requires for fruiting. The fungus's dependence on mature forest ecosystems makes it particularly vulnerable to fragmentation, as smaller forest patches cannot maintain the stable microenvironments necessary for its survival.
Habitat
This mycorrhizal fungus forms symbiotic relationships with coniferous trees in mature, undisturbed forest ecosystems, particularly favoring acidic soils rich in organic matter. It typically fruits in late summer to autumn in montane and boreal forest environments where soil conditions remain consistently moist.
