When I scoped Alan’s collection (Still need to post the micrographs) I tried Smith’s book, he doesn’t have any other possible names unless he somehow badly mixed up the description & key with P. luteopallida which has the right kind of spores, but is described as very small species with a light colored cap…

I think there are probably lots of undocumented Psathyrella in CA still.

were these from our BAMS/Pt. Reyes Fair, Darv?

They were never scoped to confirm just what they were, or weren’t.

It sounds as though we need to be looking a bit harder at these, or finding a new western name for them.
Thanks for pointing out the discrepancies in micro, Byrain.

Doesn’t anyone care

That this species has spores different than Smith’s description? Hayline spores without a germ pore is a pretty striking difference from pigmented spores with a germ pore. Just read Smith’s description & look at his illustrations then compare with image 303914.
