Asco on Pistacia terebinthus leaves
Enrique Rubio, 21-01-2010 20:43
Enrique RubioHi to all:
This asco seems to form amphigenous stromata (or is only a blackish subiculum?) on Pistacia terebinthus old leaves in Extremadura (SW of Spain). The pseudothecia are black, superficial, sphaerical, up to 250 micr. of diameter, and they seem to be glabrous. 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 ?

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.
