Peziza cf. lividula
Viktorie Halasu, 08-07-2016 17:43
Viktorie HalasuHello again,
I trying to find a name for this Peziza, ca 2 cm diam. Found on a warm locality in lowland, shadowed wet forest path, much sandy (probably calcareous) soil.
Excipulum consists only of textura globulosa, smaller and more angular cells at the outer side, but I didn't see any clear border between medúlla and ectal excipulum.
Asci pleurorhynchous.
Paraphyses with yellowish content, slightly clavate, not curved.
Spores elipsoid to fusoid-ellipsoid, with 2 guttules and sometimes a few small ones around them, (16,4) 18,2-20,3 (21,2) × (8,5) 8,7-9,5 (10,1) um, Q = (1,8) 2-2,2 (2,4) (sporeprint in water).
Ornamentation: dense small warts, non confluent, 0,5-0,8 um wide, ca. 0,5 um high, often higher around poles. Sometimes the spores look pseudoapiculat, I'm not sure, if it is not fully developed ornamentation or standard.

Could it be Peziza lividula (although without violet tones)? It is usually described with flat apothecia, not deeply cupulate like this one. P. howsei looks similar too, but it should have middle layer of t. intricata, that I didn't see here.
Thank you very much for advice.
Viktorie

Re : Peziza cf. lividula
I do not recognize P. lividula on your photo and the spores ornamentation should be more pustulate.
