I think that it is rather about a basidiomycetes: Guepiniopsis buccina

Re:Orange-yellow discomycetes on Ulmus
Many thanks Jean-Louis, I think you're right. Well then, I hope I have some excuse, Persoon described it as Peziza buccina...

Re:Orange-yellow discomycetes on Ulmus
Oui pas un discomycete mais l'image n'est pas typique de Guepiniopsis buccina ? Peut-être un dacrymyces ??

Re:Orange-yellow discomycetes on Ulmus
Thanks for your opinion Robert. I have an article on Dacrymyces from the Web (R.F.R. McNabb (1973) - Taxonomic Studies in the Dacrymycetaceae VIII. Dacrymyces Nees ex Fries - New Zealand Journal of Botany 11:461-524), but I think there's not enough details for more exact treatment... It could be even D. stillatus with 1-3-septate spores and with very variable appearance.
