Peziza with olivaceous hymenium

could someone give me an advice on this Peziza, please?
It was found today on soil in a very wet place (forest with Salix, Acer, Fagus, Picea, Fraxinus), North Bohemia.
Apothecia 7-22 mm in diameter, 2-7 mm high, sessile, plane to cup-shaped, rounded, oval or irregular shaped from upper view, hymenium smooth, olivaceous to black (in old fruitbodies), outer surface brown, finely granulose. In groups.
Spores (from spore print, measured in water) 18-21 x 9,5-11 micrometers, hyaline, with +/- regular isolated warts, containing guttules (sometimes 2, sometimes more, sometimes 1 big and few smaller ones).
Asci 380-450 x 14,5-17,5 micrometers, cylindric, with 8 uniseriate spores.
Paraphyses 3,5-4,5 micrometers broad, apex slightly broader (up to 6 micrometers), septate.
Textura globosa-angularis.
With the key in Nordic Macromycetes I came (after few compromises) to Peziza limnaea, but its spores should be ornamented by "low comma-like warts". With Hohmeyer I came somewhere to depressa... but my spores are bigger and colour should be also different.

Re : Peziza with olivaceous hymenium
Chère amie myclogue,
L'espèce me fait penser à P. polaripalulata (J. Moravec) K. Hansen. Toutefois l'ornementation sporale, pour celle que je peux voir, me semble différente. La chair et les parapphyses correspondent, bien que j'ai observer, sur une récolte que je décris dans Fungi non Delineati une medulla de textura intricata. Voir annexe.
Amicalement
