Hello.Here is a Hymenoscyphus growing on a small dead branch (hardwood), in a wet place.
Excipulum of textura subprismatica, becoming ± a t. subglobulosa at the base, mixed with clavate cells.
Paraphyses without VBs.
Asci without crozier, IKI+ (bb)
Spores 13-16 × (3.2) 3.5-4 µm
Any suggestion?

Re : Hymenoscyphus
Hi Nicolas
with this spore characters I the absence of VBs and croziers sounds strange. Can you give photos of them? The apothecia are completely stalkless? What diameter?

Re : Hymenoscyphus
Thanks Zotto for your reply. I'm going to make a new prep, now the specimens are dried.
Apothecia are very short-stalked, reaching 1.5 mm diam.

No crozier (after me).

Re : Hymenoscyphus
No doubt! That could point to Ph. fulvidulum which is usually dark-coloured, but when there were no VBs in the living paraphyses, then this is ruled out.
