Hello friendsI have this Peziza on Fagus 6-7 cm, without latex and furfuraceous excipulum. I think it fits Ok with P. arvernensis, but I have no clear the differences with P. pseudosylvestris (guttules, flesh strates, paraphysis ??).
Asci euamyloid, with croziers.
Spores finely ornamented, without reticulum, no guttules, (14.6) 15.7 - 16.9 (17.7) x (7.8) 8.5 - 9.4 (10.1) µm; Q = (1.6) 1.7 - 1.9 (2.0) ; N = 50; Me = 16.3 x 8.9 µm ; Qe = 1.8.
Paraphysis capitated and moniliform.
Flesh with 5 layers, outside to inside: subglobose small, subglobose-angularis big (< 200 µm), intricata, subglobose-angularis big (< 200 µm) and intricata (subhymenium).
Could you help me to separate this species from P. pseudosylvestris?
Thank you.
Miguel Á. Ribes
