As we were unable to find a suitable genus for this collection we asked Stip Helleman, who thinks it could be "Patinella sanguineoatra" like and sees similarities with this observation:

Adam Polhorský has confirmed that it is the same species, he thinks the brown "spores" in the excipulum may be the anamorph of this species.
It will be sequenced.
Disc:
The discs are sessile, cup-shaped, with whitish hairs on the edge, the underside is dark in color, and the hymenium is yellow-green in color.
In KOH the excipulum discolors brownish, photo 13.
Structure:
Strange textura globosa, brown
Hairs:
Incrusted.
The incrustation disappears in KOH.
Asci:
Measured in water: 64.5 - 74.79 (74.8) × (8.9) 8.93 - 10.18 (10.2) µm, Q = (6.9) 6.93 - 7.3

Paraphyses:
Cylindrical with septum, branched.
Spores:
Hyaline, with two "spots" of guttules.
Measured in water:
(12.5) 13.4 - 15.69 (15.7) × (3.9) 4.2 - 5 (5.1) µm, Q = (2.9) 3 - 3.5 (3.6)
