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.

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?

Enrique Rubio, 22-03-2023 16:57

Re : On Betula branch?

yes, Margot, something like this

Lothar Krieglsteiner, 22-03-2023 19:16

Re : On Betula branch?

isn`t it written thyriothecia?
Yours, Lothar

Enrique Rubio, 22-03-2023 19:31

Re : On Betula branch?

thyriothecium or thyriothecia (plural). One h was missing

Lothar Krieglsteiner, 23-03-2023 07:49

Re : On Betula branch?

could be the reason why Margot did not find the term in the internet ;-)
Yours, Lothar

Margot en Geert Vullings, 23-03-2023 13:48

Re : On Betula branch?

Hopefully this will be good enough?

Margot

Enrique Rubio, 23-03-2023 14:02

Re : On Betula branch?

Yes, I think is good enough.

Margot en Geert Vullings, 23-03-2023 15:49

Re : On Betula branch?

Thanks Enrique and Lothar for the missing H
