One of the most distinctive purple Cortinarii, this is also the Type species for Genus Cortinarius. It is not a good example of a typical Cort, but is certainly memorable and a beautiful mushroom to observe. There are no local species with which it could be confused, but according to Harrower (2015) there are several other species in this section in at least Australia, New Zealand, South America and SE USA.
