Hello.A cerebriform ascomycete sprouting scattered

Ascomes jaunâtres de diamètre 1mm max.
Textura globulosa.
Spores bisériées dans les asques.
Asques avec crochets, IKI+ bleu.
Paraphyses cylindriques larges de 2 µm, apex arrondi, sans gutulle.
Spores 7,4-10,7 x 2,8-3,5 µm pour N= 23 - Q=2,2-3,4 aves toutes petites gutulles.
Une idée ?
Merci d'avance.
Yannick

a Mollisia, perhaps (without comparing accurately) M. olivaceocinerea.

Re : Asco sur Carpinus ou Fagus
A section would be necessary, is the excipulum hyaline also near the base?

Re : Asco sur Carpinus ou Fagus
Thank's a lot Lottar and Zotto.
Here are more information :
Textura sous-hyménium : textura angularis with hyalin cells. Thickness 60-70 µm.
Textura excipullum ectal : textura globulosa with brown cells (on all the excipullum). Thickness 30 to 50 µm in the middle.
Margin made with hyaline cells.

Re : Asco sur Carpinus ou Fagus
O.k., the spores look to me like a Mollisia, not Pyrenopeziza. Then the paraphyses should contain refractive VBs (in water).

Re : Asco sur Carpinus ou Fagus
No, I don't see refractive VBs in paraphyses. May be dead ?

Re : Asco sur Carpinus ou Fagus
I will sequence it.

Re : Asco sur Carpinus ou Fagus
Ha, if you have that possibility!
If you have your disco fresh, I would be surprized if all paraphyses were dead. You chekced it in water?

Re : Asco sur Carpinus ou Fagus
Hello. I have checked again but all paraphysis are empty.

Re : Asco sur Carpinus ou Fagus
So let's wait for the sequence. It would be good to show a photo, because only then I can estimate this observation (whether they really were alive).
