Jacques FournierBonjour à tous,
j'ai là un disco qui m'intrigue, que je soumets à votre perspicacité.
Je joins la description, en Anglais car j'espère des commentaires de Zotto!
Merci d'avance.
Amitiés,
Jacques

Re:Durella?
Dear Jacques

this is Pezicula frangulae.

Very good presentation, could be made by myself :-). Glad to see that you use Lugol! With Melzer you would not have obtained the redbrown reaction typical of Pezicula. Wonderful your photos of the ascus apex before and after KOH, also the living guttulate spores! If you saw living asci you will only find such aseptate guttulate hyaline spores inside them, so the yellowish septate spores are overmature.

Cheers
Zotto

Re:Durella?
Dear Zotto,

thanks for your identification. My error is a good example of the possible bad use of terminology. What I assumed to be immature hyaline ascospores were in fact nice living ones, while the yellowish, septate ones were nasty overmature ones. Thanks for the lesson.
Kind regards,

Jacques
