Bonjour,
Sur tige morte d'Equisetum sp., vers 2000 m d'alt. Massif de la Vanoise.
Ascospores : 22-27 x 10-12,5 µm, elliptiques, hyalines, remplies de guttules, lisses. Dans IKI, quelques gouttes rouges de glycogène visibles.
Asques : cylindriques, grands, brusquement et courtement stipités, avec crochet, à appareil apical positif à IKI, contenant huit spores obliquement unisériées.
Paraphyses : cylindriques, contenant de nombreuses guttules.
Je pense qu'il s'agit de Stamnaria laetissima ?
Merci d'avance !
Andgelo

Re : Stamnaria sp.
S. laetissima has subsessile apothecia and longer & narrower spores. I guess your fungus fits S. austriaca. Then the substrate should be Equisetum variegatum, which appears to be possible.
Could you please provide collection data, I would like to note them to your pics.

Re : Stamnaria sp.
Bonsoir Zotto,
Merci beaucoup.
J'ai été trompé par la longueur des spores, qui me semblait bien grands pour austriacum.
En effet, les spores sont trop larges.
Je ne peux pas identifier l'Equisetum, mais en effet E. variegatum ressemble à ce que j'ai vu.
Voici la donnée : 02/09/2021, Commune de Bessans, lieu dit ''Avérole", 45,304656 7,075367, alt. 2075 m. herb. pers. AM2109024.

Re : Stamnaria sp.
You are right, 23 µm is the known maximum. When I take your figured free spores as 22-23 µm long, the width would be 8.5-9.5, so they should in fact be longer to meet your spore width. But the spores in IKI would be 10-11 µm long with that scale. You don't have a scale to your pics?

Re : Stamnaria sp.
how complicated! I cannot interpret the figures in the tables. A simple 10 µm scale would do, I am used to measure with a ruler and calculator.
