Recognized by sight: Could be the same thing as P. longipes since most of the other similar taxons are, if not more work needs to be done to determine how it is different…

Smith had 4 species in that part of the key, Psathyrella longipes, P. fragilissima, P. elwhaensis & P. thomii. The differences are mostly bs and subtle, Smith used mostly spore shape and size, but Coprinopsis maracescibilis (=P. marcescibilis) has spores with variable shapes and sizes. P. fragilissima & P. elwhaensis have since been determined synonymous with C. marcescibilis and P. thomii has larger spores and may look something like obs 65825 & obs 97004. As far as I am aware, no one has done any work on P. longipes concerning this issue and Smith failed to include P. marcescibilis, I personally can’t find any concrete differences in the literature and even figuring out what Smith meant with the differences between P. longipes, P. fragilissima & P. elwhaensis seems like an exercise in futility…
