Plateau des Tailles, fange à 600 m d'altitude. En groupes sur branche morte de Vaccinium uliginosum.
Apothécies immergées puis érompantes, excipulum noirâtre (text. glob.) mais hyménium blanchâtre.
Asques 8-sp, spores irrégulièrement bisériées, IKI -, X 12-13.5 µ, sans crochets.
Spores globuleuses, hyalines, non guttulées mais + ou - granuleuses, très variables, (4.5)-6-15 x (2)-4.5-6 µ.
Paraphyses apparemment peu nombreuses, hyalines, ne dépassant pas les asques, sommet renflé + ou - en ampoule X 2.5-5.5, parfois surmontées d'un téton.

J'ai consulté l'étude de F. Dicosmo & al., mais pas d'idée...

Amitiés - LUC.
