Bonjour,

Trouvé sur bois mort et décortiqué de feuillu (sur un ancien dépôt de bois au bord d'une route à 622 m), apothécies 0.2 - 0.6 mm, turbinée à l'état jeune, puis étalée, à hyménium brun-noir, surface externe concolore, asques 160 - 240 x 10 - 15 µm, crochets+, octosporés, IKI-, spores 57 - 92 x 3 - 3.5 µm de diamètre, multiseptées, paraphyses filiformes et ramifiées au sommet. Merci de me donner une idée.

Elisabeth

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.
