Bonjour à tous,Récolté chez moi, en bord de route ombragé, sur feuilles mortes de Carex divulsa subsp.leersii. Roche-à-Frêne, Manhay, prov. Luxembourg, Belgique, 29.02.12.
Pycnides éparpillées, immergées, noirâtres à la loupe, à peine érompantes (ostiole), lisses, 350-400 µ de diamètre.
Péridium text. ang., mince, brun clair mais noirâtre autour de l'ostiole.
Conidies brun clair, non guttulées, lisses, non septées, (4.8)5-6.5 x (1.5)1.8-2 µ
J'ai fouiné dans la doc que j'avais: pas d'idée.
Amitiés - LUC.

Re : Coelomycète s/ Carex divulsa subsp.leersii
This will not be much help Luc, but I have made many 'coelomycete' collections on Carex (and also on Poaceae) which do not correspond to any descriptions I can find
W.B. Grove's "British Stem and Leaf Fungi" can sometimes help with a name, but how many true species are involved seems far from clear
best wishes

Re : Coelomycète s/ Carex divulsa subsp.leersii
Hi Chris,
Yes, it seems there's still much, much work to be done for those fungi. Especially the ones with microconidia.
After checking Ellis, I've checked in Grove (I got it from Cyberliber). And when one has no idea, Saccardo, it takes way too much time!
And yes, there's the problem of: how many are true species, but also, how many are yet poorly described/studied, if at all. Stutton (1980) was very careful himself...
Cheers - LUC.
