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?
Photo 1 (x 400) - 1 graduation vaut 2,51 µm
Photo 2 (x1000) - 1 graduation vaut 1,01 µm
Merci,

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
