Nectria on Quercus

Maren Kamke, 22-01-2019 21:17

Good evening,
I found this nectria species gregarious on an decorticated oak-stem. Pale yellow 0,02 mm diameter. Ascomata not collapsing, with solitary, flexuous hairs, covered with a tomentum with thickwalled hyphae, acompanied by a white Anamorphe. Ascospores 1-septate and verruculose.
Regards Maren
