HelloSur bois mort d'Alnus en milieu humide (bord de ruisseau)
Apothécies : orangée-roussâtre, très convexes, parfois crénelées, de 0.3 cm à pied court.
Réaction amyloïde peu marquée voire nulle d'où mon interrogation sur un représentant du genre.
spores ellipsoïdes-fusiformes, multiguttulées
(8.8)-10.8-(14.7) x (3.2)-3.5-(4.1) N=15
Q= 3
Paraphyses à nombreuse granulations (réfringentes ?)
Croziers +
Excipulum angularis
J'ai écarté P monticola pour la couleur et P. epiphyllum qui a des spores plus grandes.
J'ai retenu P. imberbe mais un autre genre (Cudoniella ?) est aussi possible.
Merci pour vos remarques.
Salutations

Re : Phaeohelotium imberbe ?
I have a folder "imberbis aff. inamyloid" which could fit your specimen.
H. imberbis = Phaeohelotium imberbe is something like a Cudoniella, if taking a narrower genus concept, although it was never combined there.
From my HB 7469 (drawing) I have a sequence which clarified that this is not conspecific with H. imberbis with amyloid asci.

Interesting feature. Quite closely to my own finding fifteen miles away

Re : Phaeohelotium imberbe ?
Also dépt. Herault? Would be good to know the exact place, also the date.
In my case the wood was ring-pored, Fraxinus or Castanea. You are sure with Alnus?

Re : Phaeohelotium imberbe ?
Yes. I'll sent to you name and localisation of the place.
Rotten branch is not easy to identify. But finally, I'm not really sure of Alnus.
I'll join pics of the piece of wood.

Re : Phaeohelotium imberbe ?
Thanks for the data and the correction of the wood. Corylus is scattered-pored but Fraxinus and Castanea are ring-pored.
