Looks too black to me, more possibly something of the Tympanidaceae if any disco at all.

Dear Mr Laessøe,
didn't you by any chance notice a gelatinous layer on the external surface of these anamorphs? Macroscopically it reminds me on this fungus: http://ascofrance.fr/search_forum/53107 , immature pyknids have this shiny black appearance, later they become taller and produce a ball of conidia. Also the branching of conidiogenous cells is similar.

I cannot see an outer gel layer but there seems to be gel in the tissue - the pycnidia/conidiomata are rather shiny and soft textured
