Bonjour,Pourrait-il s'agir de Tricharina gilva?
Trouvé le 24/11/09 sur un sol sablonneux pauvre en terre végétale, isolé.
Apothécies: 9mm, Ø x 5 mm, cupuliforme et de couleur orange.
Duvet blanc à l'extérieur de l'excipulum, poils bruns en touffe sur le bord supérieur, dimensions 180x225 x 10-13(19) µm, poils avec une extrémité arrondie.
Asques: 200-240 x 8-10 µm. J-
Parapfyses d'une largeur de 4µm avec un sommet élargi jusqu'a 7µm; colorant rouge-brun dans Melzer
Spores lisses, 15-16 x 8-9 µm
Merci d'avance.

Re:Tricharina gilva?
Les poils sont assez surprenants pour un Tricharina.
Et la couleur aussi.
Peut-être T. fibrillosa mais je crois que l'espèce a émigré dans un autre genre.

Re:Tricharina gilva?
Yes, Moravec transferred that species. to Pseudaleuria. I haven't seen any molecular evidence that the transfer was necessary, though the Index Fungorum accepts it. The spores and the imperfect state fit Tricharina. Yang and Korf credited the epithet to Currey, but Currey's name in Peziza is a later homonym, and the correct authorities change to Tricharina fibrillosa (Massee) Chin S. Yang & Korf (Art. 58, ICBN).
NO, I made an error. We never did get spores of T. fibrillosa to germinate, and had no recent collections, so there is no known Ascorhizoctonia state for this species. Would be nice to get this in culture and get it deposited in a reputable culture collection. We discovered that even old (±20 year) dried specimens have ascospores that can be germinated, so even if you've dried your collection you can probably get the spores to germinate! If it doesn't produce an Ascorhizoctonia state then maybe Moravec is correct!
