This name is from the same paper as Parasola conopilus, if you want to use that name you should use this one too. Otherwise you should use the former name, Psathyrella marcescibilis (= Psathyrella fragilissima, Psathyrella elwhaensis, possibly P. longipes, & a few other names). I think our concepts of the Psathyrellaceae genera will be turned upside down in the future…

This looks a lot like a psath to me… in fact… all of the C. marcescibilis photos online look like Psaths to me…

“Walther et al 2005 found that Coprinellus and Coprinopsis “appear to be paraphyletic in their current definition”. They concluded that more species of Psathyrella must be included in future studies."
