Cortinarius aureofulvus  M.M. Moser (1952)                                                    *Collection: Europe

This species can be interpreted almost as a twin to Cortinarius cedretorum with the habitat being the primary difference. Cortinarius aureofulvus is known from montane conifer forests with calcareous soils. Both species feature a yellow orange cap contrasted by a slightly bluish context. Unlike cedretorum, this species has almost no reaction to alkaline solutions on the context. Moser has recognized it from Western North America with multiple collections.

Mature collections have more saturated colors. Collection of young fruitbodies.

Spores: 10.2-12.3x6-7.3µ very coarsely verrucose KOH5%: blood red to purplish on cap, banal on context.
