are your images of these up on MO, Christian? If not…;)
Do yours have umbonate caps?

Yep, I’ve been going through some literature. Entoloma nitidum is a European thing. We should not use that name. I like E. trachyosporum.

Oh cool

I was just going to ask what your collection was growing under. These browner-capped ones (like Debbie’s, too) fit better with my concept of E. trachyospora, which has had a good year (lots of it at Albion I).

Noordeloos’ (2004) descriptions and photographs indicate a more blue-hued cap for this species, as well as lamellae that are distinctly pink (presumably independently of spore maturity).

He also mentions that Castellano and Largent identified some Rhodocyboid-spored things from the west as E. nitidum, a determination that Noordeloos didn’t support.

what was the date of the collection?
