Created: 2012-02-26 00:07:33 EST (-0500) By: Byrain Summary: Im… …not getting anywhere with these either. My guess assuming there is no pleurocystidia is Psathyrella subgenus candolleana section candolleana.

Created: 2012-02-25 17:19:37 EST (-0500) By: Ron Pastorino (Ronpast) Summary: 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.

Created: 2012-02-25 14:08:05 EST (-0500) By: Byrain Summary: . 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. http://www.sciencedirect.com/... Edit: On P. proxima which has different sized spores. http://www.cybertruffle.org.uk/...
