Petit disque poilu sur Urtica
Louis DENY,

Touvé près de Belfort, altitude 350m.
Sur tige morte d'Urtica dioica, très petit disque (diametre 0,1 - 0,3 mm), blanc, vite translucide.
Marge couverte de petits (10 - 20 X 1,5 µ) poils fortement recourbés
Asques 40-50X 6-7µ, négatif au Lugol,
Spores 7-11µ, extrèmités pointues, grosses et petites guttules, OCI=3/4.
Paraphyses cylindriques, Structure globulosa/angularis,
La forme des poils et l'habitat m'a conduit au genre Unguiculella, mais je ne suis pas sûr de ma détermination.
Merci d'avance pour une une idée.

Re : Petit disque poilu sur Urtica
I recommend to compare U. incarnatina, but the paraphyses are also hooked there (the same for hamulata and eurotioides). U. incarnatina differs also in asci with amyloid ring.

Enrique, Zotto
Many thanks for the hint. I rechecked ascus ring with a more recent lugol, and I now can see a weak blue reaction. This is then most probably U. incarnatina.
Thanks again

Yes, in living asci strongly compressed but I see it also
