Re : Nectria
Voir plutôt dans des genres comme Cosmospora. Mais Christian va répondre.

Re : Nectria

Hi Joseba,


Informations are lacking : is there a stroma ? did you test chemical reaction (KOH, acid lactic) ?


How are asci ? paraphyses ?


If you can show ascomatal wall, it would be better.


For me, Cosmospora species are excluded. With such ascospores, it could be closed to N. balansae (but this one is stromatic), but you must give more informations.

Re : Nectria
Hi to all,
Alain is right, this fungus is not Cosmospora.
At first, we have to know if the striate ascospores come from the red ascomata.
Morphologically, this collection resembles Neonectria but I think that it is too old to be correctly identified.
Moreover, there are several fungi on this collection,  which does not facilitate the identification, it would be nescessary to sort out.


Regards,
Christian

Re : Nectria
Gracias a los dos  por vuestro interés

He vuelto ha hacer  2 pruebas y no veo nada  nuevo.

Los apotecios no tienen reacción a KOH     ... no dispongo de Aácido lacteeo para probar.

The conidium in the bottom right of the final image is that of Sporidesmiella hyalosperma (= Sporidesmiella hyalosperma). See http://www.ascofrance.com/forum/34197/bipolaris for more information . . . .
