On Betula branch?
Margot en Geert Vullings, 21-03-2023 09:37
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.

Hi Margot
Maybe Stomiopeltis betulae?

Re : On Betula branch?
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.

Re : On Betula branch?
I think it would be good if the fruiting body is really a tyriothecium. Maybe a very shallow horizontal section would help you.
Margot en Geert Vullings, 22-03-2023 16:24
Re : On Betula branch?
My apologies, but I cannot find on the internet what tyriothecium is. I have very little knowledge of Ascomycetes. What should i see? Like on your site the first picture at the bottom?

thyriothecium or thyriothecia (plural). One h was missing

Re : On Betula branch?
could be the reason why Margot did not find the term in the internet ;-)

Hopefully this will be good enough?
