Asco sur feuille de lierre (Hedera helix)

Pas de soies, ce qui ferait éliminer Colletotrichum trichellum.
On dirait qu'il s'agit d'un champignon imparfait car je n'ai vu aucun asque. Par contre, je pense avoir trouvé une seule spore qui est elliptique : 6x4,5.
Qu'en pensez-vous ?

Re : Asco sur feuille de lierre (Hedera helix)
Bonsoir Bernard
from its general appearance I would say this is Boeremia hedericola (= Phoma h.); extremely common on Hedera. The micro shots do not really confirm this, but one can often find these fungi without viable conidia.

Hello Chris,
A big thank you for your reply. I also think for conidian form even though I have not actually seen conidia.
Best regards !
Bernard
