Re:Hypoxylon multiforme?
Difficult to say with so few elements, but it looks like H. cohaerens.

Re:Hypoxylon multiforme?
Hi Vasileios,
H. cohaerens is specific for Fagus. Otherwise its main difference with H multiforme is the germ slit length on ascospores: short in multiforme, spore-length in cohaerens, best seen in KOH.
You can visit http://pyrenomycetes.free.fr/ for more informations.
Best wishes,
Jacques

Re:Hypoxylon multiforme?
I believe both H. multiforme and H. cohaerens (along with H. truncatum and H. annulatum) have all been transferred to the new genus, Annulohypoxylon by Y.-M. Ju, J.D. Rogers & H.-
M. Hsieh.

Re:Hypoxylon multiforme?
Hi Andy,
you are perfectly right as to the new name Annulohypoxylon but I told Vasileios to visit my website, which has not been updated since this change....names change but fortunately fungi do not much ..
