On Betula branch?

On the same betula branch as of the Trimmatostroma we saw very small black fungi, about 1 mm.

We do not find what this could be?

Thanks in advance.

That was also our thought, we looked at approved sightings and saw asci narrower than we see and the spores more pointed. On your site it fits wel, thanks a lot Enrique.

I think it would be good if the fruiting body is really a tyriothecium. Maybe a very shallow horizontal section would help you.
