Bonjour / Hello.Voici un Helotiale qui me pose problème. Espèce récoltée parmi des mousses et des hépatiques, au bord d'un ruisseau, mais non greffée aux mousses, plutôt aux petits débris (aiguilles d'épicéa, feuille morte de Vaccinium...)
Apothécies Ø 2-4 mm
Excipulum ectal de textura primastica. Asques 95-105 x 8-10 µm, sans crochet (difficile d'être affirmatif à 100%), à 8 sp. bisériées (pars spor. 40-50 µm), à anneau apical IKI+ (bb), type Hymenoscyphus. Paraphyses sans vacuole, à sommet parfois difforme. Spores ciborioïdes, 12,2-15 (19) x 4-5,5 (6) µm, parfois avec 1 cloison (y compris dans l'asque), avec de rares guttules (1-4).
Une idée ?

English description
Ectal excipulum of textura primastica. Asci 95-105 x 8-10 µm, without crozier (not sure at 100%), with 8 biseriate spores (pars spor. 40-50 µm), apical ring IKI+ (bb), Hymenoscyphus type. Paraphyses without VBs, with some twisted apex. Spores ciborioid, 12.2-15 (19) x 4-5.5 (6) µm, sometimes 2-celled (including in ascus), with rare LBs (1-4).

Re : Hymenoscyphus-like species
Did you compare my Hymenoscyphus pezoloma = Pezoloma herbicola nom. prov.?
Needs to have croziers and is more white, but otherwise quite similar. Also quite unspecific to the substrate.

Re : Hymenoscyphus-like species
Indeed, it seems that your H. pezoloma is close to this species. My apos were all yellow and stipitate, and the content of the spores seems to be a bit different...
In my previous description, I ommited to mention that the cells of excipulum do not react in Lugol reagent.

Re : Hymenoscyphus-like species
Did you tgry with Congo red to be sue about the croziers? If the fungus is still fresh and in bon etat, a section should give a clear result.
The apical ring is a bit too narrow for this Pezoloma species. Looks more like a true Hymenoscyphus. But without VBs is strange.

Re : Hymenoscyphus-like species
I will check again for the croziers.

Re : Hymenoscyphus-like species
I confirm that asci do not have any crozier (see pictures)
