Black asco on thin branches?
Mirek Gryc, 28-02-2020 19:06
Hi

Found today along the forest road, on the branches of a cut bush.
As you have probably noticed, this group of mushrooms is not well known to me, so please help me identify.
Negative reaction to KOH.
spores:
(22.2) 22.9 - 30.3 (31) × (6.6) 6.8 - 7.9 (8) µm
Q = (3) 3.1 - 4.1 (4.2); N = 12
Me = 25.8 × 7.3 µm; Qe = 3.5


30.95 7.94
25.84 7.16
23.87 6.84
24.37 7.34
22.90 6.56
24.81 7.21
22.18 7.11
24.64 8.05
28.84 7.05
27.65 7.18
30.32 7.28
23.63 7.89

Hello Mirek

might the bush have been a Ribes? Your fungus looks rather like Dothiora ribesia. Compare with:



Best wishes

Re : Black asco on thin branches?
Hi Chris
Your type seems very likely :)
I collected these mushrooms in a hurry, returning home, so there are no photos from the area. It was only at home that I noticed that it was something interesting.
The place where these mushrooms are found is close to my home, so I'll check everything later.
Thank you very much
Mirek
