Bonjour,
Sur tige morte d'Osmunda regalis, en tourbière.
Apothécies de 0,3-0,8 mm de diamètre, jaune vif, courtement stipitées.
Asques : 65-70 x 6,5-7,5 µm, cylindracés, à appareil apical hémiamyloïde de type 'Calycina', avec crochet, contenant huit spores obliquement bisériées.
Paraphyses : cylindriques, larges de 2,5 µm, contenant une grosse vacuole jaune vif.
Ascospores : 10-12 x 2,4-2,9 µm, fusiformes, avec une cloison, guttulées, hyalines, lisses,
Poils : peu visibles, très courts et grêles, sinueux.
Je me dirige vers les Pezizellaceae mais je n'ai pas réussi à trouver le genre ni l'espèce...
Merci d'avance pour votre aide.
Andgelo

Re : Helotiale on Osmunda
Hi Andgelo
interesting! I am not sure whether it is a Calycellina/Mollisina or Calycina.
The spores are at least partly 1-septate already in the living asci, which is more typical for Calycina, and also spore shape reminds me more to that.
Allophylaria filicum is excluded by the colour and amyloid apical rings and 1-septate spores.
Allophylaria campanuliformis is said to be close to A. filicum, but I have no clear concept.
Helotium aureolum could be a synonym, but the spores are too long to fit your fungus.
So it remains: no idea.
Is the site high in the mountains?
