Psathyrella all the way. The reason I posted the photo was to see the
reactions on the slimy pileus. Good call both of you. My thought too
went from Strophariaceae to Psathyrella, but the internals confirmed
it right away.

In fact it is one of the varieties of spadiceogrisea, which is known
for having a “saponaceous” pileus. Interestingly, and somewhat
disappointingly, no Psathyrella author has discussed the obvious
presence of gelatinous matter on the pileus – it is not suspended in
it, like some of the ixo-… derms, but clear gelatin granules show up
clearly above the subglobose hymeniform pileipellis cells.

The pileus had me thinking Strophariaceae until I looked at the images closer. Stipe and gills looks good for Psathyrella!
