Assessment Notes

Justification

Cortinarius caperatus is a widespread, edible, ectomycorrhizal webcap in northern Europe and North America but also less frequently distributed throughout the rest of 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).
