Lirellae on Quercus lignum

Hello all, I wonder if anyone might be able to help with the identity of these lirellae among pycnidia on the lignum of a dead Quercus?
The spores were hyalaline, 3-5(6) septate, 20-26 x (3.5)4-5.5 µm, the ends +/- pointed, Paraphyses were slender with no swollen or pigmented tips. KoH + Lugols appeared to give no reaction.
The spores are too pointed for any lignum Opegrapha species but despite going through Boehm's Hysteriaceae key I can find nothing that matches.
Help appreciated!
With regards,
Jenny
