Tarzetta?
Yatsiuk Iryna, 05-09-2014 15:48
Yatsiuk IrynaHi everyone!

This fungus was found on the ground near mosses. Fresh fruitboidies rather small, 0,5-1 cm in diameter. Unfortunately, I didn't examined it microscopically in fresh state, and in some time it was covered by a mycophilous fungus. So I couldn't see very well tissues and separate asci. But asci are for sure non-amyloid.
It resembles me Tarzetta cupularis, but spores are mostly 1-guttulate and somewhat smaller (17,1-19,8*11.7-12,7). What do you think?
I also attach photo of mycophilous fungus, maybe someone can recognize it?

Best regards,
Irina

Hi Irina.
Well, it's difficult to propose a name. It looks like a Tarzetta, but spores with only one guttule is unusual (in living state) for this genus, and the spore is indeed too small for T. cupularis.
Did you check the ascus base to verify if crozier are present or not?

Re : Tarzetta?
Hello, Nicolas,
Thank you for the reply!
All spores on my photos are in dead state. In other mount I've seen several bigger spores (20-21*12,5-13) and many smaller ones (various size). You can see them on photos below
Yes, there are croziers.

With best wishes,
Irina
