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.

Re : Tympanidaceae
Hi Elisabeth & Adam

to ensure Alnus requires a radial section I miss longer radial rows of pores and false radial rays. Could be Salix?

I do not know the specie sbut agree with Adam.

Re : Tympanidaceae
Thanks aswell Elisabeth.

Please keep the specimen, it would be nice to have a record outside of Slovakia.

Atleast S.uncinata is quite plurivorous. In Slovakia it`s occuring through lowland dry Pinus-Quercus to montane Sorbus/Alnus forrests.

Re : Tympanidaceae

Hello Zotto


Unfortunately, I can't make a better cut, the wood is rotten.
