The 2-celled spores measure 8.3 - 9 × 3.5 - 4.1 µm. IKI negative.
Does anyone know what this is? Probably something quite common. Venturiaceae?

Hello,
What do you think about "Mycosphserella punctiformis "?If there was no name change there ?

Re : Pyrenos on Quercus leaf
Thanks for the answer -- that does seem like a good suggestion.
The spores are a bit wide with this one, though. But if measured from the septum, the width is 2.7 - 3.2 µm, which might fit better. I'm not sure which measurement style is preferred in this case (center vs. max width).

Re : Pyrenos on Quercus leaf
Dear,
According to Corlett, annotated list names in Mycosphaerell, your measures are reasonable.There is a study in Mycosphaerella by Andre Aptroot, but I not use that one.
Best,
