Re : Ciboria betulicola?
What a nice collection! To clarify, better micros would be necessary.
If you have the spores a bit larger and without measurements, I could better see the contents. It seems they are 1-nucleate but if you have more photos this could become
clearer.
Also needed is the IKI reaction of the ascus apex and the croziers at their base.
C. betulicola has indeed smaller spores, e.g. in Elliott 1973. In my folder there is one with living spores of8,2 - 9,4 x 3,6 - 4,7 µm.
C. betulae hase slightly fusoid, warted spores and lacks croziers. It grows on seeds instead of catkins.
Stop: Now I looked at the substrate, it looks to me much like Salix male catkins that lost their flowers. So this is Ciboria caucus. If you tell me place where you found it, I will put these data to the photos.

Re : Ciboria betulicola?
Thank you, there were also Salix caprea nearby, even though birch was dominating. This was collected in Helsinki, Finland.

Re : Ciboria betulicola?
Can you please be a bit more precise, was it inside the town, in which part of the town?

Re : Ciboria betulicola?
Inside Helsinki city limits, humid broad leaf woodland, birch, Salix caprea, ferns. Exact spot is N=6677572.179, E=389648.141 (ETRS-TM35FIN). Is this useful? Helsinki, Keinumäki.

I transferred to 60°13'11.825" 25°0'29.298" and find it in Viikin arboretum.

Re : Ciboria betulicola?
Yes that is correct, it is a large dendrological arboretum where some parts are left more or less unattended and in quite natural state.
