Psathyrella circellatipes (Edited)

Should have an absent to rudimentary yellow partial veil, not a well developed white inner veil that is appendiculate. It should also have setae on the pileus similar to Parasola conopilus.

Edit: Also, I think I should clarify that P. circellatipes keys out in Smith’s Psathyrella book with the species with rudimentary to absent veils, subgenus Psathyrella. Your observations won’t key out to this subgenus having a well developed veil, but we would need pleurocystidia details to accurately assign one of Smith’s subgenera.
