At the time the id was solely based on the appearance, since someone suggest the name based only on the photos. After I made some “bad microscopy with my bad equipment at the time” and could see some features, which I compare with those of “Champignons du Quebec” (see the link at my comments). More recently I saw the description in A. Melzer’s website and everything matchs nicely.
Related to your question, some times I use isotonic saline, but I don’t see any big difference, from the pure water.

Nice job!

I have not heard of this species, and it is quite beautiful. Those spores look coprinoid no doubt! When you moistened them, did you use isotonic saline? Unless so, I am told my one that you may get inaccurate measurements. Is your ID solely on the basis of spore size?

I think that the microscopy confirms the identification suggested by Antonio of Psathyrella vinosofulva.

seems to be a good proposal not only to the macro but also to the spores, which according Roland Labbé (see here) are" ellipsoides, lisses, avec pore germinatif, gris-brun foncé, 10,9-14,1 × 5,6-7,5 um; Q=1,7-2,2". I may have a dried specimen and I’ll try to make some slides to observe under the microscope. If successful I’ll update this observation.
Thanks, Antonio, for your comment.

found Psathyrella hirtosquamulosa. Maybe it has some similarities with these specimens, but judging by the spores dimensions (Spores 6-7,5(8) x 4,5-5, 5(6) x 4-5 µm, seen at vielepilze) it is another species. Thank s, Jonathan M, for your proposal.

Any idea about the species?
