Cortinarius rufoolivaceus

Description

Cortinarius rufoolivaceus is recognized by the winy-red color of the cap and olivaceous of the gills, which cannot escape the attention of any collector.

This species is very rare in nature, so in some European countries, it was listed in the Red Book as an endangered species.
