It was a late night frustrating microscopy and I quit before getting the necessary info for a confident ID. Sorry. One day I may come back to it.
The nivea seemed a more likely ID than virgineus because of the habitat, so I gave it a “Could Be”.
As for the differences between the genera you mention, I am quite ignorant. Apparently, Dasyscyphus has been synonymized with Lachnum (so Dasyscyphus virgineus is Lachnum virgineum). Today I found a paper by Ain Raitviir on Dasyscyphella (http://www.ib-pan.krakow.pl/...) and he says that “It comprises
species having characteristic hairs which are thinwalled and warted as in Lachnum Retz., but possess 1 or 2 smooth glandular cells apically.”
Even if what I found is a Dasyscyphella, it’s not necessarily nivea; there are quite a few species described in Raitviir’s paper.
Thanks for your inquiry; I learned a little trying to answer your question.
And BTW – can some point me to a source that clearly states what is the difference between Dasyscyphus, Dasyscyphella, Lachnum, and Lachnella? Or Hyaloscypha for that matter…
Did you check the differences between this and Dasyscyphus virgineus? The paraphases shape, and the ornamentation of the hairs on the back of the cup?
