Biology:List of Cortinarius species

Short description: none

The cortina around the fungi which gives name to the genus.

With around 2000 species,^[1] Cortinarius is the biggest genus of fungi that form mushrooms. Apart from a few species such as C. caperatus, many even so-called edible species appear to have very similar species that are at least inedible if not poisonous, or otherwise may differ in edibility geographically.

The following species are recognised in the genus Cortinarius:^[2]
