I would appreciate your opinion on this yellow Hymenoscyphus growing on a little twig, maybe of Rubus idaeus.
Asci 114-125 x 11-12 µm, H+, bb.
Ascospores (16.6) 17.7-19.2-20.8 (23.1) × (4.2) 4.3-4.7- 5 (5.9) µm, Q = (3.37) 3.70-4.07-4.54 (4.94), without cilita, not septate.
Paraphyses with strongly refractive guttules.
Using Bernard´s key, I have arrived to H. calyculus, but OCl is lower than 5 (but many pictures at the internet also show spores with lower OCl).


thank you very much.
I have ommited Phaeohelotium and went directly to Hymenoscyphus...
