Indeed, Encoelia pruinosa )or now Sclerencoelia pruinosa) would also be my first option.But it should occur on living trunks. There should be lots of crystals outside, which is probable because of the pruinose surface.
Spore size could be larger, but apo size seems to be variable.
To clarify whether it is Salix or Populus needs to look at a radial or tangential section for homo/heterocellular radial rays.

Hello Edvin,
very interesting fungus.
The photos are with phase contrast as you write. Why? I do not use it at all and would much prefer to see "normal" photos. I think I am not alonè with this (?).
Best regards, Lothar
There is enough contrast when mounting in water, especially when cells are alive. Look recent contribution by Elisabeth.
What you mean with polar thickenings of the spores, I assume you mean the light polar region seen especially in one spore. I am unable to say in photos with phasecontrast, but I could see clearer without that device, maybe polar oil drops.
I don't understand the grainy background but otherwise the photos are splendid.
So from the scale I get 11.5-13.5 x 2.6-3.3 µm which would fit well with other collections.
Would it be possible to share some apothecia for research?
This found is very interesting for me because from Europe I have seen only specimens collected on 19 century in Norway. It is important to undestand if Sclerencoelia pruinosa in Northern America we have studied with molecular methods, and current yours European specimens turn into the same species. In N-Am pruinosa is parasitic and it is possible that it is introduced from Europe where it does not destroy its native host. I would like to see, if there is stromatic tissue under apothecia - it was clearly developed in historical specimens and deviating character comparing with Sclerencoelia fascicularis.
Please, could you send a piece of your specimen to:
