Dasyscyphella nivea?

Hi all,
I would like an opinion on whether this can be definitively called Dasyscyphella nivea.
Marginal hairs are septate and have granular roughening on the lower parts, but are smooth at the ends. The ends slightly inflated, up to 3.3µm wide.
Asci: IKI+, with (I believe) croziers, 47-55 x 3.9-5.1µm
Spores hyaline, fusiform, 5.6-8.8 x 1.7-2.5µm
Paraphyses somewhat lanceolate up to 2.8µm wide.
From a hardwood branch on the ground, probably Oak.
Apoogies for the poor photos.
Ethan

Re : Dasyscyphella nivea?
Hi Ethan,
The genus Dasyscyphella is for sure correct.
Did you notice any crystal in the hairs ? D. nivea , which is fairly common in Europe on the underface of hard logs, genrally shows such crystals.
Amitiés. Michel

Re : Dasyscyphella nivea?
Michel,
Thank you so much for your reply. I do see crystals. They are hyaline, sometimes typically diamond shaped or irregular and can be quite large. I have included a couple of images. There is also an image of the paraphyses extending beyond the asci.
