On wooden litter under Crataegus

Hello.

Under Crateagus I found this cup today, 10 mm in diameter.

At first - because of the Crateagus - I thought of of Monilinia johnsonii, but after digging it out it did not show a long stipe and it obviously was growing on some debris of wood or grass. Spores 9(10)-11,5 x 5,4-6 µ, smooth, Asci ~180-190 x 10-11 µ , 8sp, paraphyses swollen at the end
What did I find?

Thanks for your comments!

Sincerely,  Chris

Re : On wooden litter under Crataegus
This is surely operculate. First, I would check if the asci are IKI-positive (Peziza s.l.).

Re : On wooden litter under Crataegus
Thank you folks.

And Yes, Lothar, you are right. IKI-positive.

Here's two more pics in Lugol.

Cheers,  Chris

Re : On wooden litter under Crataegus
Addendum: the place of discovery is at a urination site for dogs - which might lead to Peziza moravecii, with such paraphyses: cylindrical, 2-3 µm wide, septate, with a rounded tip widened by up to 5 µm. Only the spores seem too small with 10-11.5 x 5-6 µ. In the literature there is a Peziza perdicina (Velen.) Svr?ek, which is apparently synonymous with it, with smoother and shorter spores (10-12 × 5-6 µ), which would fit exactly here.

Thank you folks for looking at my little brown fungus!
