Hello,this Peziza was collected in Slovakia, in altitude about 400 m asl., on soil in a ditch, 18 June 2016. Ascobolus viridis, Scutellinia legaliae and S. trechispora grew near it.
Apothecia 4.5-5 mm in diameter, sessile, brown, rounded or irregular, plane, warted on the outer surface.
Spores 19-21,5 x 9.5-10.8 micrometers, ellipsoid, hyaline, with a gelatinous sheat, without guttules, ornamented with warts of unequal size (up to 3 micrometers broad), sparsely distributed on the spore surface.
Asci 287-340 x 15-18 micrometers, amyloid, cylindrical, octosporic, uniseriate,
Paraphyses septate, containing vacuolar bodies, 3.2-4 micrometers, apex strongly broadened, 7-10 micrometers, rounded, sometimes slightly bent.
Excipulum of textura globosa, cells 14-34 micrometers broad.
It resembles eg. Peziza acroornata in some characters (macro, eguttulate spores with sheat), but the ornament seems different.
Thanks, Zuzana
Hola Zuzana.
Podría ser Peziza granularis. http://www.ascofrance.fr/search_forum/35625

I'm not totally convinced that the warts can be seen as "real" ornamentation, because they are dispersed very unequally over the spores. I have seen warts on spores also on Helvella species, may be due to an overageing of the fruitbody. So it would not be too astonished about that being P. granularis, despite the spores being somehow warty.
best regards,
Andreas
What is it, if not ornament?
If it would be some mess on the sheat, I shouldn´t be on the spores inside asci...

Dear Zuzka,
I didn't want to say that it is not an ornament, but that I have some doubts that the ornament is significant in this case.
Compare the foto of the ascus and spores of Helvella lacunosa - this species also has smooth spores and here the ornament is even more evenly dispersed on the spore than in your case.
I also don't want to say that the ornament is insignificant - only that one might have to take into account that it might be an artefact or an unusual "production", whatever reason this may have caused.
best regards,
Andreas
thanks a lot.
Such a large genus, and it makes such treacheries in addition :-)
Unfortunately I found only two apothecia, one of which wasn´t mature enough to provide sporeprint, so I couldn´t test more fruitbodies.

This species was initially described by Heim & Rémy under the name Aleuria granulosa f. laricina, so considered as a form of Peziza granulosa Schumach.
I'm not convinced that Zuzana's collection could be P. granularis in the sense of Donadini, which has smooth ascospores (also a bit wider), and no vacuolar bodies in the paraphyses after my own collections.
But I have no name to propose!
your Cahiers is usually among the first books I check when trying to determine an operculate ascomycete. But I wasn´t able to imagine my fungus (which measured 4.5-5 mm and one of the fruitbodies was mature enough to give a sporeprint) could reach 20-35 mm as you give for sublaricina. The species looks also very different in the photo. Unfortunately I have no other own collections of (mature) little brown Pezizas for comparison.
