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.

Re : Nectria on Quercus

Not a Nectria (KOH +). Look at Bionectriaceae, especially Lasionectria.
