Ciboria on Betula catkin

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!
