Mathias HassHi everyone, Found on attached branches of top pa
Est-ce que quelqu'un peut m'aider à déterminer cet ascomycéte ?
Récolté aujourd'hui sur une feuille morte de Yucca. Ascomata rond, très nombreux.
Diamètre ascomata : 150 à 200 µm
Asci : 55 – 75 x 12 – 20 µm.
Spores : 17 – 21(23) x 6 - 8 µm., elles ne sont pas colorées et il n'y a pas de cloisonnées
Merci d'avance de votre aide.

Question before the holidays (maybe a bad time) - no response
I try again. Maybe someone can help?
Piet Bormans
do you have a closeup-photo of the perithecia?

Thanks Maren and Alain for your response. The spores form don't fits well with Guignardia istriaca. My knowledge is insufficient to determine this species. Maybe someone is interested, then I will send it to him.
Regards,
Piet
