These very densely, gregarious apothecia were growing on the hymenium of a very decayed resupinate, poroid fungus on wood of Fagus sylvatica at 1000 m of altitude. The apothecia are white, shortly stipitate by a stout, broad, cylindrical pseudostipe. The white hymenium is briefly cupulate, later aplanate or only slightly convex, 200-500 microns in diameter. Excipulum downy, as the margin.

The inconspicuous marginal cells are cylindrical or slightly clavate, smooth or finelly incrustate, but not verrucose as in Cistella species. Ectal excipulum of hyaline, roundish, angular to prismatical cells with no inclusions or VBs. Paraphyses optically empty, with no VBs.

Asci 8-spored, IKI b or rb, with croziers.

I think it could be near to Calycina guttulifera from Zotto's folder.

What do you think?

Thanks again

Re : Calycina guttulifera ?

This really looks like C. guttulifera, but I fear it is a collective species, the samples included i  my folder are too heterogeneous.
Maybe yours fits best the find by Patrice Tanchaud from 10.IX.2015 in lacking VBs and a blue apical ring. my 6787 was IKI purely red.

From 6787 we have a sequence (ITS and LSU). It clusters in Leptodontidium near L. trabinellum, but these fungi have VBs.

Re : Calycina guttulifera ?

Bonsoir Patrice

Oui. Je pense que ton champi est le même, qui as les cellules marginales avec un petit épaississement apicale.
