Zotto has remarked on iNaturalist that this taxon has been repeatedly misidentified as Hymenoscyphys scutula in GenBank, if not other genetic databases.

I add my ITS-analysis showing the problem. The lack of marginal teeth is remarkable and could point to a different species, but the available sequences, which are predominantly from outside Europe, all appear to lack morphological data. Possibly behind these deviations exist several species.
I forgot that I have a folder "coronata aff. no teeth", with 5 European collections without teeth, but with the microscopy (mostly in living state) very similar to collections with prominent teeth.
