Enrico Tomschke, 20-01-2022 20:40
Hello Everybody!
I Need help with this little Ascomycete on Peltigera sp. A Litte White-cup Fungus on the Thallus of Peltigera.
Asci J- biseriate.
Spores:
(9.1) 9.11 - 10.4 (10.5) × (3.3) 3.4 - 4.4 (4.7) µm
Q = (1.9) 2.2 - 2.86 (2.9) ; N = 13
Me = 9.8 × 4 µm ; Qe = 2.5
Does anyone see something similar in the past?
Thank you everybody for help!

Re : Little white Cup Fungus on Peltigera sp.
I suppose this is Pezizella epithallina. I have it in the Laetinaevia-folder in Calloriaceae.

The asci should react hemiamyloid. If you use Melzer it will be negative, in Lugol red, after KOH blue in both reagents.
