Hi Chris,

Is there something about the photo that definitely says not
Diatrype disciformis?
I understand that
D.disciformis has the synonym of
Hypoxylon disciforme, and that whilst it mainly appears on Fagus, it is not all that infrequent on other deciduous trees, including Betula.

Again, for the benefit of us novices, is there something about the photo that says not
Biscogniauxia nummularia? - I've browsed numerous images and can't readily see any visible (macroscopic) differences between
B.nummularia, and D.stigma. (I understand that
Biscogniauxia is specific to Fagus only).
I'd be very grateful for your thoughts.
Regards
Mike.
