…not getting anywhere with these either. My guess assuming there is no pleurocystidia is Psathyrella subgenus candolleana section candolleana.

The spores were mounted in KOH.

They did not seem to turn Hyaline in KOH.
I tried the A. Smith tome also but didn’t get anywhere. but it is difficult to navigate those keys.

I was trying to key it out in Psathyrella Species of North America, I think maybe subgenus candolleana section candolleana. Though I need more info. What are the spores mounted in? Do they turn hyaline in KOH (Within 30 minutes or so?).

Also, the text says to look at P. proxima, but I can’t find that species anywhere excluding this which wants $30 to view it.

Edit: On P. proxima which has different sized spores. http://www.cybertruffle.org.uk/...

No Pleurocystidia that I could find.
