Birken-Gürtelfuß

Cortinarius bivelus is a mycorrhizal agaric fungus in the family Cortinariaceae, assessed as Data Deficient (DD). Like other members of the genus, it forms ectomycorrhizal associations with forest trees and produces a characteristic cobweb-like cortina veil when young. Insufficient data on its distribution and population size prevent a reliable conservation assessment.

Blauer Schleimkopf

Cortinarius salor is a webcap mushroom recognised by its slimy, blue-violet cap and paler gills that mature to rusty brown as spores develop. It forms ectomycorrhizal partnerships with broadleaf trees, especially beech, in European temperate forests. Classified as Vulnerable, this species is threatened by the loss of mature, undisturbed deciduous woodland.
