Gills purple when young, then turning brownish with age. Pronounced webbing when buttons are opening. 5% KOH on mature caps darkens the brown color.

… very similar to mine. I have no immediate plans to sequence this because I have so many Inocybes and Entolomas planned. If I start getting serious about Corts, I’ll be stretched too thin.

I am interested to hear your comment on this species. This seems to be what passes for C. alboviolaceus here in the east, but what I have seen in the west is clearly different. Did you happen to sequence this?
