Bonjour à toutes et tous,Un ami m'a envoyé ces photos, prises sur une branche morte de prunellier (Prunus spinosa).
Auriez-vous une idée et quelle est la raison de ces gouttes laiteuses ?
Grand merci d'avance !
Bernard

Re : Asco inconnu sur Prunus spinosa
Hello Bernard, looks like spores (more likely conidia) protruding through the ostiolum. Not uncommon at many ascomycetes incl. anamorphs when ripe and moist weather. Your pictures do not give a hint to me what species this could be.
Yours, Lothar

Re : Asco inconnu sur Prunus spinosa
Hi, Lothar !
Great thanks for your message.
I asked the observer if he had observed anything under the microscope and he sent me this (nematodes or conidia?).
Best regards,
Bernard

Hello Bernard,
definitely conidia. Maybe somebody can say more now, but not me ...

Many thanks Beatrice!
I think it's the right choice! I will ask my friend to check.

Re : Asco inconnu sur Prunus spinosa
Bonjour Bernard,
Your photos do not represent the brown bottle-shaped conidiomata of Dermea cerasi.
Maybe we have to do with beta conidia of some Diaporthe sp.

Re : Asco inconnu sur Prunus spinosa
Ah ? OK, Bernard !
Grand merci pour ton hypothèse que je vais aussi communiquer à l'observateur !
Je lui demanderai de vérifier s'il voit des Dermea cerasi typiques dans cette station !
Amitiés et excellente fin d'année à toi !
