Not sure why you don’t think this is P. piluliformis. The microscopic features agree quite well with Observation 64818. I am not sure which other species have spores like that, the tiny gray spores are pretty unique. And the simple cheilocystidia/pleurocystidia is also unusual in Psathyrella.
It would be useful to make a spreadsheet with the data on all species in each genus, so you can search on an attribute like spore size and get a list of all the species that have that feature.
