Good evening,
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.
