Sclerotiniaceae on the wood

Please about help with determination. On the part of wood of Alnus or Quercus, from the Czech Republic in july.
Apothecia cca to 5 mm in diam., sclerotium not see. Excipulum consist of cells of textura globulosa, cells 13-20 x 11-14(18) um, paraphyses 75 x 1,7 um, asci IKI + (BB), 60-80 x 5,4-6 um, ascospores (8)9-10(11) x (2,8)2,9-3,5(3,6) um, Q=3, N=20. I was looking for it between Ciborinia / Botryotinia etc., but it will maybe something else.
Thanks.

Re : Sclerotiniaceae on the wood
I think a Moellerodiscus. In dead state not easy to give a name. Your asci and paraphyses are dead. The latter probably contain VBs when alive, the former are much larger when turgescent.

Re : Sclerotiniaceae on the wood
Thanks, very interesting ... I have a question, when species are possible in central Europe on this substrate from this genus?

Re : Sclerotiniaceae on the wood
Do you mean where they can occur, or at which time of the year? I know Moellerodiscus more in warmer or milder regions of Europe (e.g. atlantic), but my Moellerodiscus sp. HB 2938 on Alnus leaves and fruits made in summer 1985 is temperate (from Stuttgart), as is M. tenuistipes on Filipendula.

Re : Sclerotiniaceae on the wood
Ou, sorry, typing error, I have mean which species, no "when" ... if it was good for anything, I can try to sequencing it.

Re : Sclerotiniaceae on the wood
If you wantz to sequence it you should try to clarify some more characters, especially the iodine reaction under oil immersion and the presence of croziers. That would help in a conclusion, because the molecular knowledge is still poor.
