Hymenoscyphus?
Wim de Groot, 09-12-2023 20:57
We found these little stalked discomycetes on a rather thick decorticated branche of (most probably) quercus. It was difficult to acquire spores, measuring about 14x4 µm.

Re : Hymenoscyphus?
These data are not enough, one needs paraphyses, ascus base, iodine reaction, excipulum. Apo size? Anyway I guess H. conscriptum on Salix (see other post these days). Quercus has ring-pores and thick radial rays, you can easily check that.
