can well be Psathyrella hirta. Thanks, Byrain and Elsa.

Outer veil

P. papilionaceus doesn’t have such a dense outer veil (On the cap surface, inner veil refers to over the gills), many Psathyrella have an outer veil though. The white shaggy stem is also wrong for P. papilionaceus which would have a reddish/brown pruinose stem from caulocsystidia.

Ok, it could be a

Psathyrella. But again the description of P. papilionaceus in “mushroom expert” mentions that the stem is “finely hairy”.

Small specimen

I’m not sure if you’re considering this part of the observation, but the smaller specimen looks like Psathyrella not Panaeolus.

I wouldn’t think this is P. antillarium with a veil leaving an appendiculate margin, that would make P. papilionaceus more likely. I guess you could consider P. rubricaulis too which should have sulphidia on the gill face and a strongly hygrophanous cap, but that may only be an Asian species…

I see what you mean …

and I think you are right. It must be P. papilionaceus for both observations.
Thanks, Elsa.

I don’t know

much about P. Antillarium but I read that the cap was of a lighter color. My references were http://www.mykoweb.com/... look at the description and photos below and google images as well.

I don’t know if P. papilionaceus is the best choice for this observation (I’m not very familiar with this genus), but it is certainly a good proposal for my other observation 121794 from the same location, where at least one of the specimens has a wrinkly cap, which seems (looking for the photos available for that species) a distinguish feature.
