I think this fungus shows some similarities to Discostroma but I couldn't find a species that has ascospores with 3-4(5) transverse septa, is J- and grows on wood. Maybe someone here has a suggestion?
The host is most likely Fraxinus (dead branch on the ground). Asci: (85)105-115 x 8-10 µm, +- uniseriate, p. sp. = almost the whole length of the ascus, IKI - (even when pretreated with KOH). Ascospores: apparently with a slimy sheath when still inside the ascus, 18-22(23) x 4-5.5(6) µm, hyaline, with 3-4(5) transverse septa (most ascospores are 3-septate though). Paraphyses: hyaline, filiform.
Best wishes and many thanks,
Gernot
