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.

Weiden-Dickfuß

Cortinarius urbicus is a robust, fibrous-capped mushroom in the Cortinarius genus with a silky brown cap and rust-spored gills at maturity. It inhabits coniferous and mixed forests, forming ectomycorrhizal associations with spruce, pine, and occasionally deciduous trees. This fungus obtains nutrients by trading sugars with its tree partners in forest soil environments.
