and everyone else for weighing in. For me the most confusing thing is that at least some descriptions of bipellis mention the lined cap. But I suppose the radial wrinkles qualify. Online photos (allegedly bipeliis) vary with respect to this trait.

I added a photo of the gills.

particularly the two in pic #3, are the source of my confidence… but I’ve dialed it back to Promising because of the other more “normal Psathyrella” looking caps.

Jacob, can you…

provide reasons for your high level of confidence regarding P. bipellis? Just wondering what trait(s) point decisively toward this species. In the previous comment I mention a couple things that seem to point away from bipellis.

Spore size fits bipellis.

But bipellis is reported as having purplish gills. I didn’t notice any purple tinge on these gills. Also, these caps were a bit larger than 5 cm and lacked marginal lines (both traits reported by MushroomExpert). But, checking some internet sources, bipellis was the closest thing I could find.
