Merci de me donner une idée.

Re : Tympanidaceae

Super! I had this species 2 times. I think it`s the same genus as Zottos "Skyttea/Durella" uncinata. Sequence places it unresolved within Helotiales. Despite the strong ionomidotic reaction and rounded inamyloid ascus apex its unrelated to Cordieritidaceae. https://drive.google.com/open?id=1yJpGqMX0kDA6zHe3BJIUxGp2KwcVcrTA

Re : Tympanidaceae

Great, thanks a lot!

Ionomidotic reaction KOH 5% , for the bark, I think it's Alnus.
