Dasyscyphella nivea?

Bonsoir tous

I'm fairly confident this is D. nivea - for some strange reason I don't think I have come across it before.

Hairs minutely ornamented below, smooth above; paraphyses narrow, not or barely longer than asci; asci with croziers, IKI blue; ascospores 6.4-8.7(9.5) x 2-2.5µm. Crystals rather frequent - the one in the image is c. 17µm across (edge to edge) the larger "twin".

Comments welcome.

Amitiés

Chris

Re : Dasyscyphella nivea?
Yes, no doubt. I think I saw it always on Quercus or Fagus stumps or logs. Really frequent.

Re : Dasyscyphella nivea?
Many thanks Zotto. Yes this was on the heartwood of the underside of a fallen Quercus branch.
