Bonjour, Marie-Rose D'Angelo (Société Mycologiq

Hola a todos
Alguna idea para este ascomiceto amarillo en corylus avellana .
Esporas 9-13 (16) X 4.5-5, elipsoidales con pequeñas gutulas en los extremos, alguna septada.
Ascas 145-170 X 8-9,5, IKI+, base bifurcada.
Parafisis cilinfricas, con solo algún septo en la base.
Gracias y saludos
Javier
You may in some literature find the spores to be septate but this concerns overmature stages. The mature asci of this species ejects non-septate spores
The spores usually contain a larger LB in each half together with some small ones. To be sure you should look at the excipulum whether it is gelatinized and the hyphae oriented at a high angle to the surface (in section).
I believe that the species belongs in Calycina, as C. citrina, from its microscopy but also from its DNA.

But have a look at the excipulum, please.
