The characteristic protuberances on the cortical cells I do not see. Perhaps you could compare "Calycellina" indumenticola, but that is a pure guess.

With thanks Otto but not Calycellina indumenticola, although the genus gets closer. Checked ten other species and all not even close, much larger spores, septate or the apothecia distinctly unlike these examples. I'll try to find a Calycellina key unless you can advise where this might exist. I couldn't find this genus in your folders, looking at Hyaloscyphaceae, but perhaps lookimng in wrong family.
Apprecaite your help, Tony

Hi Otto,
I checked all 45 species and your suggestion stands out the most by far but under the C. indumentocola aff. folder (wide spores). I would suggest most elements fit, inc. paras tips, asci size, spore size (mine a little larger) except that the description shows no guttules/drops, Ectal looks good, even the yellow exudate the same and appears to have a obconical base. On Salix, mine Acer but I guess that's possible. I think this shows a hemiamyloid reation also. So if I was a betting man ....   Incredible that you can pick this species out among what could have been 100's.    Probably as far as I can go I guess.   Thanks again   Tony

It is really not easy and much remains a guess. Yes, the guttules in the spores. The more collections of a presumed species you have the more you knw about its variation, at least if you have sequences as well.
