Urceolella crispula?

Hello everyone
They grew on dead shoots of Helianthus tuberosus.

Comparing with the photos on Zotto's disk, I am almost certain that this is this species. However, I am wondering about the slightly larger size of the spores;
(9.3) 10 - 11.45 (11.5) × (2.4) 2.7 - 2.9 (3) µm
Q = (3.3) 3.4 - 4.1 (4.8) ; N = 8
Me = 10.6 × 2.8 µm; Qe = 3.8


Croziers (+)
IKI (Lugol) = bb
The hair in KOH with a strong concentration dissolved almost completely.
Regards
Mirek

Hi Mirek

I think the spores are fine. I had to extend the size in my folder name a bit since there is a sample inside with up to 11.5 x 3 µm.
