Nice that you had these sequenced! I think this is the first confirmed occurrence of Pluteus americanus west of the Rocky Mountains

Great job!

The cap surface does actually remind me of Pluteus americanus, but I do not see any blue coloration on the basidiocarps. The species in the Pluteus plautus group can have hygrophanous caps, but in most cases the surface of the cap has a more hispid texture, as is it is covered with hair.

Here the surface is mostly smooth with only squames at center. It does look more like something in sect. Pluteus.

Microscopical data will point you in the right direction
