Cortinarius caperatus is a widespread edible ectomycorrhizal webcap, in northern Europe and North America but also less frequently distributed throughout Europe. There is no evidence of decline. It can be locally very abundant where suitable habitat exists. Therefore, it is assessed as Least Concern (LC).
Why suggested for a Global Red List Assessment?
Cortinarius caperatus is a locally very common webcap in northern Eurasia and northern North America. Widespread in boreal, hemiboreal, subalpine and artic zones, while rare in the temperate zones. The area of occupancy (AOO) of this species is much larger than 2,000 km², and its extent of occurrence (EOO) is much larger than 20,000 km².
Population and Trends
The population size is likely to be very large since this is such a widespread species with a very broad ecological niche. There is no indication of any decline.
Habitat and Ecology
Cortinarius caperatus is a common terrestrial ectomycorrhizal webcap in coniferous forests with spruce and pine, in deciduous forests with beech and oaks, in subalpine forests with birch and in alpine areas with dwarf birch.
There are no major threats to this species.
No conservation measures are needed for this species since it is widespread and there are no major threats to it.
