Avec cette ornementation, il faut exclure le genre Otidea et rechercher vers Sowerbyella.
Je me demande si S. radiculata ne conviendrait pas

Re:Otidea / Sowerbyella
Thank you François, Jean Pierre
I had excluded S. radiculata by the habitat (not Juniperus / Cupressus) and the lack of stipe, but it is the first time I see it. Ok, S. radiculata.
Best regards

Re:Otidea / Sowerbyella
According to the papers that François has send me, I think it could be fits Ok with S. radiculata var. kewensis, which has smaller and ellipsoid ascospores compared with cylindric-ellipsoid ascospores measuring (13.5)-14-15.5-(16.5) x 7.5-9 microns in the typical variety of S. radiculata.
Thanks François,

Re:Otidea / Sowerbyella
Je ne reconnais pas S. radiculata sur cette photo. Même si je ne l'ai pas vu souvent, ça me semble différent ; la photo de Jean-Pierre est plus significative.
Cette récolte m'évoque également S. crassisculpturata. Ci-joint la photo de R. Chalange d'une récolte que j'avais étudié et dont les cractères me semblent proches de ceux de Miguel.
Sur cette récolte, spores de 14-16 x (6.5) 7.5-8 µm.

Re:Otidea / Sowerbyella
Ok, both species are very similar.
In Yao, Y-L. & B. Spooner. (2006), Species of Sowerbyella in the British Isles, with validation of Pseudombrophila sect. Nannfeldtiella (Pezizales). Fungal Diversiti, 22: 267-279, they said this about S. crassisculpturata:
"Sowerbyella crassisculpturata J. Moravec in Mycotaxon 23: 492 (1985).
= Sowerbyella radiculata (Sowerby: Fr.) Nannf. in Svensk Bot. Tidskr. 32: 119 (1938)
Examination of the Bristish specimen cited by Moravec revealed no significant character to distinguish it from other specimens of typical S. radiculata. S. crassisculpturata was separated from S. radiculata based on spore ornamentation which is 'a certain number of mature ascospores is sureticulate, but in the majority os ascospores is verrucose'.... They are very similar to those of typical S. radiculata. The characters emphasises by Moravec are considered here not to warrant recognition of S. crassisculpturata as a separate species from S. radiculata. They are, therefore, treated here as synonyms."
Anyway, boths species seem very closed, isn't it?
Thanks,
