Cortinarius viridirubescens  M.M. Moser & Ammirati 1997                       *Collections: California

Cortinarius viridirubescens is one of the most distinct and beautiful members of the California Cortinarius flora. Its greenish colors set it apart. Genetically it falls in the clade of the similarly green Cortinarius atrovirens/ionochlorus from Europe.

Basal mycelium. is distinctly yellow.
