Unknown black apothecia???
Dirk Gerstner, 07-03-2023 09:52
Hello all,
I'm completely in the dark here. I would be very grateful for your opinions.

Found on debarked Hedera_helix.
The black apothecia are approx. 300 -500 ym in diameter.
The spores are 3 times septate and measure:
Spores [95% - 14 - QPr - v - H2O(nat) ] = (9,2)9,4 - 11,7 - 13,9 x 2,7 - 4,1 - 5,4(6) µm.
The saccular ascis measure approx. 40-45 x 9 - 12.5 ym.
The reaction of almost the whole ascus in Melzers is blue.


Many thanks for your opinions


Kind regards
Dirk

Re : Unknown black apothecia???
Hello Dirk,
compare the genus Dactylospora (Sclerococcum). More problem will likley be to say something on species level.
Yours, Lothar

Re : Unknown black apothecia???
Hello Lothar,

Great, thank you very much for your quick answer.
Your hint on the genus level helps me a lot. I will look into the matter at my leisure.

The topic of this lichenised/non-lichensed genus seems to me to be extremely complex.

I quickly compared it with your mushroom of the month, as I said, the genus probably fits, but there are a lot of species.


Thanks again and best regards
Dirk
