Bonsoir à toutes et tous,Pourriez-vous m'aider à identifier cet Asco imparfait de couleur rose sur Populus canadensis ?
Conidies spiralées, vermiformes, à 10-20 cloisons.
Grand merci d'avance !
Bernard

Hello Bernard,
Maybe this one?
In Microfungi on Land Plants on page 56 (Plurivorus Wood en Bark Fungi) Helicomyces roseus: "colonies superficial, effuse, pale pink. Conidia helically coiled, filaments multiseptate, hyaline, 160-180 x 6, borne on short conidiophores. On rotten wood."

Re : Asco imparfait à conidies spiralées sur Populus canadensis
Hi Riet,
Thank you very much for your message! Indeed, I had seen Helicomyces roseus in Ellis & Ellis but I had not found any good macro photos on the net. On the other hand, I have the impression that the conidia of Helicomyces roseus are longer and narrower ...
But I think we must be in the Tubeufiales.
Best regards,
Bernard

Hola Bernard, no entiendo mucho de estos, Helicomyces roseus parece una buena opción, pero con esta morfología no descartaría un Helicoma.
Saludos cordiales.
