salut a tous, has anybody an opinion on this anamorph, growing on sambucus? always 3-septated, pointed, with lighter cells on top, very constant in lenghth with spores 16-18 x 7-8. looks quite similar to something of hysterium, but its clearly an anamorph.
i can't say much to stromata, black, embedded, more edged than rounded, 0,5-1mm. i don't think that its host-specific, because some time ago i found the same on castanea.
all best

Re : unknown anamorph
It's difficult to be sure without seeing the conidiogenous cells and conidioma, but the conidia resemble Seimatosporium to me. Do any of the conidia have basal and/or apical appendages?

Re : unknown anamorph
thank you very much! the genus sounds good. i didn't see appendages, but the collection seems to be exactly the same as in this earlier request:
