Bonjour tout le monde,
Je présente un possible Calycellina, quoique peu claire ou du genre, dans l'écorce intérieure trempée dans l'eau trop saumâtre branche morte de Pinus halepensis. Disciforme taille jusqu'à 1 mm avec petit pied intégré dans le substrat.

Asques cylindriques en massue, octosporées, biseriate, monorrincas, amyloïde 35-42 x 6-7 μ en taille. Ascospores elliptiques-fusiformes, lisses, hyalines, avec une cloison centrale spécimens matures, présentant de petites gútulas irrégulière de 8-14 (16) x 2,5-3 (4) microns. Paráfisis filiforme. Excípulo ectal structure subglobosa et prismatiques.

Re:Calycellina blanche??
Looks for me like a Hyaloscypha or related genus, but not Calycellina. It would be important to see the width of the paraphyses and especially living ones because of the vacuoles.

Are there any hairs? How looks the margin?

Re:Calycellina blanche??
I bring a bad image with the presence of paraphyses. It's hard to deepen the study of this genus

Re:Calycellina blanche??
Yes, it's not clear, but at least I see that the paraphyses do not contain VBs (refractive vacuoles) so it is surely non Calycellina.
