Maladie des feuilles du Salix sp.
Enrique Rubio, 17-07-2008 18:44
Enrique RubioQuelq'un connais cette maladie des feuilles du Salix? Les symptomes ils s'éveillent à eux d'une Taphrina, mais je ne croi pas qu'elle l'est. Lépiderme parait respectée. Quelques conidies septées en surface. Les chloroplastes paraint envahis de corpuscules hyalines polimorphyques. Je ne vois pas des asques. Peut etre un maladir virique?
Merci en avant par votre opinion.

Hi Enrique

I do not know who made this purplish structures, but I feel the conidia on your photo are the Marssonia state of Drepanopeziza sphaerioides (see in Ellis & Ellis p. 245, fig. 1107), said to be not uncommon in GB by Ellis, though they have not yet seen the apothecial state.

Many thanks, Zotto.
At least, you give me tracks to be able to look for another ascomycete...
