Dear colleauguesToday I finded very nice fungicolous Ophiostomatoid fungus, which colonise Diatrype stigma stromata. I think its something close to Sphaeronaemella, but I dont know what exactly. Also I am confused by pitted ascospores walls in my specimen. Can you advise me, what it can be?
I take this opportunity to congratulate everyone on the new 2018

Re : Fungicolous Ophiostomatoid on Diatrype
Dear Alex,
did you consider the genus Viennotidia? It is synonym for some authors with Sphaeronaemella and it would be probably an undescribed species. The closest I found is V. raphani which is on germinating seeds of Raphanus. I attach the drawing and protologue by Negru&Verona 1966.
Do you have closer images of the spores, to see germ pores etc?
I wish you and the whole community a good start for 2018!
Best regards
Martin
