Observation 150029: Cortinarius smithii Ammirati, Niskanen & Liimat.
When: 2013-10-26

Notes: I thought this was C. semisanguineus because of the mustard yellow cap and stipe.

The older caps turned browner, and sometimes a bit redder, making them look more like typical C. smithii(=C. phoeniceo-occidentalis).

Dimitar Bojantchev in personal communication said that the northern forms of this species are more variable and that sequence data shows that they are still C. smithii.

KOH rxn purple, (nearly black on cap), most pronounced on felty mycelium around stipe base.
First time I have seen this color form in the western United States.

but yes, apparently all sequence data shows that these yellow-capped ones in the PNW are merely a variant. In support that hypothesis, I will say that the older, more weathered caps did look a lot more like typical C. smithii.

Difficult to believe.
