Cortinarius flexipes is a fungus, specifically a mushroom, a small brown species in the genus Cortinarius. It is commonly known as the Pelargonium webcap because of its unusual smell of Pelargonium (the household "geranium").
This species of mushroom is found in Europe and North America. It is hygrophanous, and belongs to the Telamonia group, being thin-fleshed and having a dry cap and stipe.
Cortinarius paleaceus (Weinm.) Fr. and Cortinarius paleiferus Svrek (sometimes written C. paleifer[1]) have commonly been identified in Europe as separate species.[1] [2] [3] C. paleiferus is defined as having more widely spaced gills, and has a pale violet mycelium at the base of the stipe. Now these types are combined into one species and considered to be only varieties of C. flexipes.[4]
