Il y a quelques jours j'ai trouvé Pleomassaria siparia sur une petite branche de Betula pendula. Sur la même branche j' ai également trouvé des conidies inconnus. Je les trouvais tellement particulier que je voudrais en savoir plus. Quelqu'un peut-il m'aider?

Re : Bonjour,
Hi Piet,
it looks very much like Prosthemium betulinum, the anamorphic state of Pleomassaria siparia. You find a description and illustrations in:
Kazuaki Tanaka, Vadim A. Mel'nik, Maasa Kamiyama, Kazuyuki Hirayama, and Takashi Shirouzu, 2010. - Molecular phylogeny of two coelomycetous fungal genera with stellate conidia, Prosthemium and Asterosporium, on Fagales trees. Botany 88: 1057–1071.
Best wishes,
Gernot
