Bonjour à tous,Cela fair plusieurs fois que je ne parviens pas à mettre de nom là-dessus. Hormis un nom de genre: Pyrenopeziza.
Récolté le 13.08.11, sur tiges mortes de Cirsium palustre. Réserve naturelle domaniale de la Grande Fange de Bihain, Vielsalm, prov. Luxembourg, B., env. 550 m d'altitude.?
Apoth. sessiles, en groupes ou colonies, en coupe fermée puis aplatie, -> 0.8 mm. Marge fimbriée. Couleur gris-brun fuligineux, très sombre à l'état jeune. Excip. semblant un peu poilu ou du moins nettement furfuracé.
Exc. ectal banal, text. glob., brun. Poils atteignant 45 µ.
Asques 8-sp., sp. bisériées, IKI BB, (30) 38-50 x (5.2)6-7(7.5) µ. Crochets non remarqués ou absents.
Sp. un peu asymétriques, parf. symétriques, hyalines, huile = 2, non septées, (7)8-10(11) x (1.5)1.8-2.2 µ.
Paraphyses cylindriques, à peine réfringentes, x 2.5-3-3.5 µ p. ex. KOH nul.
Amitiés - LUC.

Re : Pyrenopeziza s/ Cirsium palustre.
Yeah, but I think I excluded that one due to the size of the spores, way too big in my sample IMO. (I corrected the data's. Meh, distraction.)
Oh, so, Bernard Declercq's key gives me Pyrenopeziza escharodes, which matches fine with the size of spores and hair, and which gives oil -> 1.5, which is a bit lower than on my sample, but noot much. Except if one has a better solution, I think I'll stick with P. escharodes.
Cheers - LUC.
