Bonjour,

J'ai trouvé cette semaine Caesiodiscus populicola, en France dans le Jura. Depuis sa découverte en Norvège, j'aimerais savoir dans quels pays elle a été retrouvée ?

Sur le forum, il y a une observation en Espagne, peut-être aussi en Autriche (Peux-tu confirmer Gernot ?).

Merci d'avance pour vos réponses.

Hi, Andgelo!

I am quite sure that my collection does indeed represent this species, yes. Nice that you found it in France as well now.

Best wishes,
Gernot

Re : Caesiodiscus populicola

Merci Gernot ! Je voulais surtout que tu me confirmes que ta récolte a été effectué en Autriche.

Re : Caesiodiscus populicola

Ah, that was a misunderstanding. Yes, I found this species in Austria.

Best wishes,

Re : Caesiodiscus populicola

I would be glad to see links to these samples. From Enrique I have photos of what is at least the same genus, as I now see. I have it under Ostropalean, ERD-7793, Molinillo (Salamanca), 24-XII-2018, on Eucalyptus camaldulensis. But the dead asci are much longer (200-225 x 12-14) and the living spores broader (26-28 x 13-14) than in the protologue. The docu is in my folder Ostropomycetidae, Caesiodiscus.
