Re-bonsoir.Voilà un très beau champignon trouvé dans une mouillère dans les PO à 1700m d'alt. sur une branche de bois (à proximité : aulnes, hêtres, bouleaux) indéterminé.
Macro :
Ascome haut jusqu'à 9mm ! cupuliforme à orbiculaire étalé. Hymenium de diamètre 6 mm max, crème grisâtre.
Excipullum furfuracé. Excipullum et stipe (jusqu'à 6 mm de haut) crème-grisâtre un peu plus foncé que l'hymenium.
Ne rougit pas à la blessure.
Micro :
Spores incurvées, 20-25x6-7 um remplies de guttules de 2 à 3 um de diamètre.
Asques 70-90x10-12 um, IKI+ dans le Lugol. Spores unisériées. Boucles +
Paraphyses larges de 4 um, septées, remplies de guttules non réfringentes.
Avec les clés dont je dispose, je n'arrive à rien de convainquant.
Pouvez-vous m'aider dans cette détermination ?
Merci par avance.

Peut-etre Tatraea dumbirensis?

In Asturias (N of Spain) is a very common species on Fagus forest.

Hi Enrique,
Many rare species can be found in Asturies , a fabulous region to be visited by Asco fans and other mycologists !

Merci pour ces réponses !
Qu'est-ce qui distingue le genre Hymenoscyphus et Tatraea ? Les spores ?

Re:Hymenoscyphus ?
A difficult question. One reason is the shape of apical ring, see here attached. It goes till the apex and there widens. Herein and in the spores it tends to the Rutstroemiaceae, while presently I have it in the Ombrophiloideae, though it isn't gelatinous. I am unaware of genetic research on Tatraea. I can imagne that it is rutstroemiaceous, but the apical ring excludes Rutstroemia. But it resembles a bit that of Hymenoscyphus fulvidulus.
Here is the previous contribution about Tatraea.
