Bonsoir,

récolte au sol, apothécie 8 mm pour la plus grande, spores 16-19 x 9,5-11 µm.

J'y verrais bien Tricharina praecox...
Merci d'avance pour vos avis éventuels.

Re : Tricharina
En poursuivant les recherches, je vois que T. ochroleuca pourrait être un bon prétendant...

A voir.

Re : Tricharina
Hi Patrice,
T. ochroleuca is a nomen dubium.
Regarding the shape of the ascospores I would suggest hiemalis, subhiemals or tophiseda. Did you use the key in the following paper? https://ascomycete.org/Journal/Article/art-0363

Re : Tricharina
Many thanks Uwe for this reference, I had not considered this publication, although it is of great importance given the quality of the work with sequencing. The spores, without guttules or granules, seem to eliminate T. tophiseda, then concluding between T. hiemalis and T. subhiemalis seems more difficult without DNA.

Re : Tricharina
Because of the spore quotient, I would tend towards hiemalis. But to be absolutely sure, sequencing would be necessary.
Best, Uwe

Re : Tricharina
We agree. Thanks.
