Didymosphaeria (?) on Vitis

Hi to all


I'd like to know your opinion about this fungus that makes globose or pyriform inmersed pseudothecia (I think the asci are not unitunicate) < 500 microns on a Vitis vinifera branch. Their protruding necks are somewhat stout and they are up to 200 microns long. Hamathecial filaments hyaline, much branched and with anastomosis. Ascospores with conspicuous striate walls. Pseudothecial walls pseudoprosenchimatous.


My guest is Didymosphaeria massarioides. What do you think?


Thans again
