Enrique RubioConaissez vous cette Pyrenomycete sur Alnus glutinosa?
Spores two-celled, at maturity one of this brown and with an longitudinal germ-slit
Ascus I +

Re:Pyrenomycete sur Alnus glutinosa
This looks like Anthostomella. Several species known with longitudinal germs slits and found on wood (e.g. anserima).

Re:Pyrenomycete sur Alnus glutinosa
Bonsoir,
Si la spore fait environ 25 X 11 µm voir peut-être vers Kirsteiniotella aetiops ??? vient me semble t-il sur Alnus.

Re:Pyrenomycete sur Alnus glutinosa
Bonsoir Robert,

Kirchsteiniotheila est un genre à asques bitunicate, et je crois que nous avons à faire avec des asques unitunicates. L'appareil apical suggèe en effet qu'il faut chercher auprès des Sodariomycètes.
Summarising for Enrique in english: i suggest to exclude Kirchsteiniothelia

Amitiés,
Bernard

j'avais déjà répondu mais mon message n'est pa passé,
It's the Enthostomella Genus, dear Enrique, let's know the microscopic data
Best wishes :)

Re:Pyrenomycete sur Alnus glutinosa
I can only agree with Christian, who is certainly more familiar with pyrenomycetes than I am.
It would be interesting to confirm us about the presence of the typical clypeus, to inform us if the immersed perithecia are growing scattered or in clusters, give us the dimensions of the brown spore cell as well of the hyaline one.

Regards,
Bernard
