Lophodermium -> Hypoderma
Viktorie Halasu, 18-09-2020 09:28
Viktorie HalasuHello,

this looks like Lophodermium petiolicolum, except for the much wider and shorter spores with high lipid contents. Am I in a wrong genus?
On Quercus robur petiole and primary vein, soc. Rutstroemia sydowiana. 
Paraphyses 1,7-2,2 um, with a few scattered small VBs. 

Thanks a lot for any advise.
Viktorie

Re : Lophodermium -> Hypoderma
Perhaps a better idea now, Hypoderma ilicinum?

edit: After checking the extant literature and this forum, I see it won't be possible to get any closer than "cf.", so I guess I'll leave it at that for the time being.
