The stromata (or the subicular tissue ?) forms superficial and circular patches up to 3 mm that include many pseudothecia

Re:Asco on Pistacia terebinthus leaves
I think could be a genus into Venturiaceae (Atopospora, Platychora...).
Many thanks for your help again

Hi Enrique,
It seems to be a bitunicate ascomycete, isn't it ?

I was looking around Venturia too.

Re:Asco on Pistacia terebinthus leaves
Oui, Alain. Je pense qu'il est bituniquée. Connais tu quelq'une sembleble espece de Venturia?

Salut Enrique,
Je n'ai malheureusement pas d'idée précise. C'est une famille que je connais très mal.
Désolé, et bonne recherche.
