Appreciate the notes on original taxon and nomenclature. You are definitely the girl to see for notes on Cortinarius :-)

This collection was so deeply purple and glutinous on the cap that I was thrown initially. Thanks again for your help and support.

Hope your season was verdant and plentiful,

I learned this species as Cortinarius mutabilis. It should stain purple when cut. Kare Liimatainen did a type study and found the type species of C. mutabilis and C. occidentalis were the same species, and C. occidentalis was described first, so it takes priority.
