Apothécies stipitées, cupuliformes, 3-5 mm de diamètre. Hyménium brun roussâtre. Surface externe un peu plus pâle, finement pruineuse. Stipe noirâtre sur plus de la moitié, assez court (2-3 mm)
Asques 130-150 x 9-10 µm, J+, avec crochets, contenant huit spores bisériées ou iirégukièrement unisériées.
Paraphyses divisées, septées, 3 µm au sommet, contenant souvent une longue goutte réfringente.
Spores elliptiques à extrémités assez aiguës, hyalines, lisses, contenant deux petits amas de granulations, 10-11 x 4,5-5,5.
Chair à excipulum médullaire de textura intricata et excipulum ectal de textura globulosa.
Je ne trouve rien de concordant dans ma doc. Il y a bien un Ciboria latipes mais je n'ai pas remarqué de plaque stromatique et le pied est décrit très long....
Merci de votre aide
Gilbert

Re:Aide pour un Ciboria
The data remind me of a find from Marais Poitevin in 2008, on bark of Populus, which I tentatively identified as Ciborinia pseudobifrons, a species usually growing on leaves. One of the characteristics were the binucleate spores. This is not easy seen, but possible in a water mount by closing a bit the aperture, or with phase contrast. Better to be seen when staining with Lugol. Thso spores are slightly attenuated at the ends. Do you have a microphoto?
Stipes were inserted on inner face of medium to very rotten bark from blackened area, no sclerotium. Ap. 3-7 mm diam. Asci with croziers, IKI 3bb, +H2O 130-133 x 7.5-8 µm, 8 equal-sized spores. Sp. *11-13.5 x 5-5.5 µm (thick branch) or 11-14 x 5-6 µm (thin branch), always binucleate, 0-4 minute/small LBs near each end or in centre. Medulla IKI-, with scattered crystals.

Re:Aide pour un Ciboria
I am not sure from your photo about the number of nuclei. The literature says for pseudobifrons
7.5-16.5 x 3.5-5 µm, so a very broad range.
