Black on Betula bark?
Mirek Gryc, 26-05-2020 09:28

Hi.
On Betula bark, I recently found a species of mushroom that I do not know.
I once saw similar ones in this forum so I thought it would be more convenient to ask you for help instead of wasting time looking.
Thank you in advance!

Hello Mirek,

this should be Helminthosporium caespitosum (= Corynespora caespitosa)

Here you can compare (pages 53-56, Fig. 6)

Hello Norbert

Very nicely prepared article. I haven't read it yet but the pictures themselves show that this is probably the genre.
Thank you very much and best regards.

Hi.
Confirmed twice :)
In that case, nothing remains for me but to thank both gentlemen!
Thank you very much!
