here I have a Biscogniauxia which I cannot determine:
Substrate: On Alnus, ca 150 cm over the ground.
Stromata: applanate, margin inconspicuous, 5-17 mm ø, surface dark-grey to black, very old turning light brown, with a black line in the substrate.
Ostioles: inconspicuous, hardly visible, often covered with black spore masses.
Perithecia: uniseriate, roundish, ovoid, broadly elliptic, elliptic or cylindric.
Spores: grey brown, filled with some oil drops, broadly elliptic or elliptic, 11-14 x 5-7 µm, sometimes uneven-rough, germ slit straight, over the whole length.
I think there are some similarities to B. granmoi which is quite common here on Prunus. Maybe you have an idea?
Best wishes,
Gernot
