Most likely something in the subgenus Psathyroides, stirps Lepidota (according to Smith).

Now trying to decide on the proper identity between P. propinqua, P. subtruncatispora, and P. lepidotoides would be a matter of spore shape and colour…

I also considered Leucopholiota. But the stalks do not show the scaly sheath on the lower 3/4. Also, like Christian writes, the gills are not white enough (white spore print). I found some smallish specimens of Leucopholiota decorosa last fall. I’ll post some pics later tonight.

This same Psathyrella appeared on mushroomhunting.org last fall. It really stumped just about everybody. The photographer also posted the pics here at Observor. The ID (same as what appears here) was eventually suggested by a Psathyrella expert.

These look pretty similar to Leucopholiota, although the gills are a little more grey.
