Ascomiceto en Corylus

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

Re : Ascomiceto en Corylus
I think it is Bisporella citrina :-)
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.

Re : Ascomiceto en Corylus
Gracias Zotto, en C. citrina es lo primero que había pensado, pero al no encontrar ninguna descripción con la base de las ascas forcadas, pensaba que podía tratarse de otra especie, es posible esto en C citrina?

Saludos
Javier

Re : Ascomiceto en Corylus
Hola Javier, this is indeed quite strange for C. citrina! Looks like being simple-septate.

But have a look at the excipulum, please.

Re : Ascomiceto en Corylus
This does not very much look like C. citrina, yes. Though a closely related species I think, the hair-like outgrowths with VBs inside, the VBs in the paraphyses, and the apical ring fit that genus.
