On Betula there are at least two species, C. betulae and C. betulicola. The spore size would fit within the lower range of the former one. About the latter one I haven't found much info.
The spores measure 9.4 - 10.9 × 4.1 - 5.2 microns. Unfortunately I didn't check the sample in IKI/MLZ or check for croziers. Is it still possible to say which one this is?

Re : Ciboria on Betula catkin
Quite small means less than 2-3 mm?
The one well-living spore looks to me like binucleate, though I am not sure.
In Fungi Canadenses (see my folder) C. betulicola is 2-8(-10) mm diam. with long stipe, and spores uninucleate.
C. betulae = seminicola has rough spores that are more slender.
So I have no idea.

Re : Ciboria on Betula catkin
The diameter of the apos was maybe max. 3 mm or so. I attached a pic of the entire catkin to give a better impression of the size. Here's also a couple extra micro pics. I'm not sure, but maybe I have accidentally photographed a crozier?

Spore.

Re : Ciboria on Betula catkin
Yes, croziers and 2 nuclei. This would fit C. coryli. How certain is Betula?

Re : Ciboria on Betula catkin
Ah, ok! If I recall correctly, Betula was the only deciduous tree I saw in the near vicinity. But I can't say I'm 100 % sure. The place would be maybe a bit strange for Corylus. I think it was acidic and fairly nutrient-poor.
But I'll have to keep this in mind and later check the place again. Thanks!
