Hi Adolf,

I will go through the list and give you any insight I can. I am afraid that in many cases the species-level taxonomy is still not settled, and in many cases the best we can do for now is to refer to “species group” rather than a single species. Hopefully this will change as we study the taxonomy of Pluteus in North America in more detail.

Western North America is especially problematic as there you have a mixture of widespread and endemic Pluteus species.

Most probably Pluteus tomentosulus

Both Fredo and Else Vellinga (personalcommunication) suggested that this is in fact Pluteus tomnetosulus Peck. I will make necessary changes when I consult them with Oluna.
I collected our MO Pluteus observations into the MO list (see the link below) and I wonder if you would be able to check our ID’s. I know that it’s not possible to identify collections from photos and drawings, but you can spot clear misidentifications. Tell us about them, please.

There are about 75 Oluna’s specimens of Pluteus in the UBC herbarium (Vancouver, BC), either accessioned or waiting for accessioning. We have MO observations only for less than a half of them. – Adolf
