Champignon imparfait sur drupe de lierre (Hedera helix)

Bonsoir à tous,Hier, j'ai trouvé dans la litière d'une chênaie-chamaie calcicole, une drupe de lierre couverte de petites apothécies immergées dans l'exocarpe du fruit.
Ce champignon imparfait montre des conidiophores fasciculés, très guttulés, portant à leur sommet une unique conidie. Les conidies sont elliptiques, très guttulées (2-3 grosses + des petites) : 8-10,5x5-6
Je ne vois aucun champignon sur drupe de lierre dans Ellis & Ellis !
Une idée ?
Bernard

This loks very interesting, the conidia remind me of Trochila craterium, but I am unaware of an anamorph of that species.

Bonjour Bernard
I would consider Cryptocline paradoxa - an anamorph of Trochila craterium (as Zotto has suggested). I think it's quite possible that the conidiomata might also occur on the fruit; many of these fungi can occur on leaves and on twigs/stems . . .

PS I have added the description (as Gloeosporium paradoxum) from W.B. Grove British Stem and Leaf Fungi vol. 2.

Re : Champignon imparfait sur drupe de lierre (Hedera helix)
many thanks Chris and Bernard! I was unaware of this. Indeed the synonymy is given in Species Fungorum. But I am unaware of a molecular proof.
