My name is Mirek and I come from eastern Poland.
In addition to Polish, I do not know anything so well to allow myself to use it.
However, because these forums do not support the font that is used in our country, I post the translation.
So I hope that we will be able to communicate with the help of an interpreter?

I have been interested in mushrooms for a long time and recently more and more Ascomycota.
Quite often, he finds species with which I can not cope.
One of them is a small Peziza found a few days ago.
It grew on gravelly, overgrown with moss, moist ground, right at the water's surface, on an old gravel pit.
The maximum diameter of fruiting bodies is about 1 cm.
It did not emit any characteristic juice.

Spore H2O (without ornamentation)
14.6 [16.6; 18.2] 20.2 × 7.7 [8.5; 9.3] 10.1 ?m
Q = 1.5 [1.8; 2.1] 2.4; N = 12; C = 95%
Me = 17.4 × 8.9 ?m; Qe = 2

Spore CB (without ornamentation)
15 [16.5; 17.5] 19 × 7.5 [8.2; 8.6] 9.3 ?m
Q = 1.7 [1.9; 2.1] 2.4; N = 15; C = 95%
Me = 17 × 8.4 ?m; Qe = 2

Just below the subhymenium is a thin layer composed of "textura intricata".
Lower (medullary ex) composed of oval cells.

I would ask for help in identification.

Re : Peziza?

Re : Peziza?

I don't really recognize macroscopically P. limnaea but the microscopical characters could fit.
Maybe P. badiofusca is another option but I don't have experience of this species.
