Cortinarius percomis* Fr. (1838)                                                             Collections: California

The Western American Cortinarius percomis* is genetically closely related to the European Cortinarius percomis, but is a different species that should be described at some point. Otherwise they share many of the same basic characteristics. Cortinarius percomis is widely recognized due to its fragrant odor. The Western American species seems to be more slender than the material typically depicted in the European field guides. Another fragrant species in California is Cortinarius albofragrans.

Spores: 10-11.5 x 6-6.7 lightly verrucose to smooth.
