Hi Enrique,
Have you verify that the old stromata are those of an Amphiporthe and not those of Diatrypella quercina ?
Your photos of ascospores are wonderful !
Your recolt is probably well known by Christian.

Re:Cosmospora sur Amphiporhe leiphaemia
Salut Alain
Non. Je ne suis pas bien sur parce que les peritheces parasités sont tres vieux et ils n'ont pas de contenu, mais autres branches voisines sont colonisées par l'Amphiporthe.

Re:Cosmospora sur Amphiporhe leiphaemia
Hi Enrique,
I think it's an interesting species!!!
could you please to make a vertical section of old stromata?
Ascospores of your specimen seems striate, this characteristic is unusual in the genus Cosmospora sensu lato. Moreover, it would be necessary to show the ascomata with hairs of your specimen and a vertical section of lateral wall.
Regards,
Christian

Ok Enrique,
We have to know its anamorphic state, we have to cultivate it for that.
Send me please your specimens dried at room temperature.
Have a nice day,
