that cracked yellow cap is more like an agrocybe than a psath. so much for superficial photo similarities!

The spore colour in microscope also says it is no Psathyrella! So I still opt for Agrocybe, even more then before.

seem to contradict the determination as Psathyrella species, as well as the mebranous partial veil, which is quite unusual in Psathyrella. Though not familiar with the american Psathyrellas, I would also see a Agrocybe species in that picture.

another name for this species is “Pseudostropharia kauffmanii”…

which gives a nod to its unusually robust shape for a psath. See Steve Nelson’s psath essay here:

Altho I haven’t yet scoped it, it does bear a striking resemblance to the Psathyrella barrowsii shown on page 137 in “Mushrooms of Colorado”; the thinner veil of my specimen seems a better match to the very similar P. kauffmanii.

I would agree

It looks more like an Agrocybe.

Not Psathyrella?

I don’t think this is a Psathyrella here…
