Calocybe

Is a good suggestion, and I have looked. I haven’t ruled the genus out per se, but I think the prevalent pileipellis type is a hymeniderm. unfortunately, I don’t have any pDAB… that would be pretty useful right now.

According to bigelow

C. highlandensis has spores too short for your specimen. Also it has siderophilus granules and is probably something in the Lyophyllaceae which makes me wonder, did you by any chance put some PDAB on it? Some groups of Lyophyllaceae have ornamented, cyanophilic spores and a tricholomatoid habit. perhaps some sort of Calocybe?

looks promising in just about every way, but it lacks clamps.

Well

The thing about the Bigelow book is that I don’t have it and can’t find a pdf. Though, Patrick has a copy at the museum. I keep landing in the same area as well. The problem with comparing this to the verrucose spored species is that most of them have pink spore deposits where this was white. The few Clitocybe I can find that have white warty spores fall way outside of the morphological parameters. Thanks for checking, Joshua! I really appreciate that.

I should really learn to read…

I looked through some european references (Moser, FAN, Swiss, Funga Nordica) and it always wants to be Clitocybe (=Lepista) irina. Your spores are much to narrow for that species but otherwise it seems to generally fit the bill. Probably something close… Does Bigelow have some other species close to it?

Do you guys know

Of any Clitocybe resource besides Bigelow or Murrill? I’m not getting anywhere fast with this thing.

Weird one

especially with those knobby-constricted cylindrical spores

Sorry

If it is confusing, the first spore photo is stained with cresyl blue. These are inamyloid, as can be seen in the third spore photo.
