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?

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
Mirek
