Asco from the ground
Mirek Gryc, 20-11-2020 17:02
Hi.
A few fruiting bodies, 4-6 mm in diameter, grew on the ground covered with leaves. Nearby, cut out Salix and Populus, further Alnus and Prunus padus. I found nothing in the ground so it looks like they sprouted directly on the ground.
They remind me a bit of Geopora/Tarzetta fruiting bodies, but I have never seen them before. On the lower, outer surface, hyaline, brittle, rather long hair is very rare.
No reaction to iodine.

I will try to show the rest in the pictures.

Spores;

(23) 24.2 - 27.1 (27.5) × (9.9) 10 - 10.6 (11.1) µm
Q = (2.3) 2.31 - 2.6 (2.7) ; N = 15
Me = 25.5 × 10.4 µm ; Qe = 2.5

24.57 10.00
24.21 10.01
23.00   9.94
24.68 10.92
27.45 11.09
26.03 10.57
23.98 10.38
24.96 10.28
25.38 10.57
26.49 10.33
27.05   9.97
25.38 10.47
26.57 10.08
25.45 10.33
27.14 10.49

best regards

Re : Asco from the ground
Hello Mirek,
this should be a Sepultariella. You can yourself look up the spore size, if it is semi-immersa or patavina (I don`t know by heart). The growth under Salix is quite typical for patavina - they are mycorhizal.
Best regards, Lothar

Re : Asco from the ground
Hi Lothar.
Oh yeah, I remember that now. It's good that you refresh my memory. These irregular and large spores confused me so much that I could not associate myself. I have microscoped Sepultariella several times, but always semi-immersa, and now I know what patavina looks like.
Thank you very much
Mirek
