Trichopeziza on wood. Betula?
Mirek Gryc, 03-02-2020 12:52
Hi

I have not yet encountered such a species, growing on the decayed wood of Betula.
Maybe someone is known?

Re : Trichopeziza on wood. Betula?
Hi Mirek

The spores would point to T. subsulphureum, but that species has usually yellow to brown lumps of exudate.

Lasiobelonium populi ined. could be a better choice. Is it possible to ascertain the wood? Did you see the bark, or can you do a radial section for checking the ladder-like pore connctions?

Hi Zotto
Once again I looked at your disk and I also found L. pupuli.
The features seem to be compatible :)
Substrate I am sure. There was bark on the top of the trunk.
Thank you and best regards.

Re : Trichopeziza on wood. Betula?
However, I have uncertainty?
During the fall, the tree cracked into three pieces. They all lay in one row. The fattest was stripped of bark, so I photographed the upper one.
The bottom one, which can be seen in the picture, lying slightly to the side, I moved personally. I wanted to see his bottom page.

I do not suspect that someone was replacing wood ??
But, next to it was also Populus, only much thicker and older.
In my forest everything is possible, that's why I made cross-sectional and longitudinal sections.

Re : Trichopeziza on wood. Betula?
Hmm, from your sections I am not sure. The best to clarify is a radial section in which the pores are hit. What your section shows is only the parenchym fibres. The pores are 3-4-times as wide, and here the connections are important, I attach two photos of Betula. Populus has much larger pits (looking like an eye, third photo).

Zotto.

You definitely overestimate my possibilities :)

Re : Trichopeziza on wood. Betula?
Yes! So it is clearly not Populus but very probably Betula (Alnus would be another choice, but I don't believe). I would be glad if you send me the collection data.
Mirek Gryc, 03-02-2020 18:58
Re : Trichopeziza on wood. Betula?
Alnus excluded! It doesn't occur here at all.
He is pleased to provide the collection details:
date of harvest: 2020.02.02
Substrate: Betula wood
location in photos:

thank you
