Hi Susana,
Immature Gnomoniaceae, probably. But it would be good to check it in a few weeks. Because quercicolous Gnomoniaceae with aseptate ascospores are not present in Europe (no Gnomoniella known, for example). Shape is not really ellipsoidal, we can think at the genus Dicarpella widespread in North America. By the way; which species of Quercus is it ?
Best wishes,
Alain
I had a chance to examine european collection on leaves from the Canarias, in 2008. So, Dicarpella fits there in ecology. Also Clypeoporthella , in spite on stems, looks similar as there is black stroma. You must see at a later stage if there are beaks formed in the ascomata.
Regards,
Dimitar
Better state, and better suggestion.
Again, this Gnomniopsis is not known in Europe, so.... I can't help you more.
Alain
