(19.8) 20.3 - 22.2 (22.5) × (3.5) 3.8 - 4.9 (5) µm
Q = (4) 4.4 - 5.7 (6) ; N = 20
Me = 21.3 × 4.2 µm ; Qe = 5.1


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

Re : Cyathicula coronata on Urtica dioica - 303628165
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.
