Calycina-like species

Encore un Helotiale problématique ;)Récolté sur tiges mortes, pourrissantes, de Carex et autres plantes herbacées.
Apothécies Ø 0.5-1.5 mm, entièrement grises, certaines se teintant de rose (bactéries ?)
Excipulum ectal de textura globulosa/subglobulosa, à cellules hyalines Ø 6-30 µm. Poils hyalins, lisses, longs jusqu'à 108 µm. Asques 84-95 x 9-12 µm, avec crochet, 8 spores bisériées (pars spor. 34-41 µm), à anneau apical IKI+ (bb), type Calycina. Paraphyses sans vacuoles. Spores subfusiformes, ± allongées, 13-16,5 x 3,5-4 (4,5) µm, parfois un peu courbées, rarement avec 1 cloison, contenant quelques guttules (OCI=1). Présence d'un corps réfringent, peu épais, sur l'hyménium.
Je n'ai rien trouvé de correspondant dans les Calycina/Calycellina, mais je me trompe peut-être de genre !

Re : Calycina-like species
Hi Nicolas
I fear you need to put this to the unidentifiable discos :-(
It is possible that i have photos of this, but I lost a bit the overview. This species has liitle characters to put it in a genus.
What about the hairs, I do not see any on the macro.

Re : Calycina-like species
What is the shape of the hairs? Any septa? thinwalled? Straight?

Re : Calycina-like species
Yes, the hairs are septate with a relative thin wall. The shortest (between 60-80 µm) hairs are straight, the longest are more flexuous...

Re : Calycina-like species
Are you sure it is not a Hyaloscypha?
