This seems both macro- and microscopically fairly distinctive and interesting to me. Maybe someone knows the species?

Re : Greenish on Betula leaf
This is Calycellina araneocincta. Very close to C. lachnobrachya but with yellow VBs and specific to Betula.
Both species are unsequenced as far as I know, only C. lachnobrachyoides is in GenBank. To base a distinct species solely on colour is unusual, therefore I wonder about the genetic distance between the two.

Re : Greenish on Betula leaf
Thanks for the info. So this time it was a Calycellina! I found Phialina lachnobrachya from our species list (apparently a synonym for C. lachnobrachya), but no araneocincta. Maybe I'll try to find more to make a sample for storage.

Re : Greenish on Betula leaf
yes, some authors follow Huhtinen to place the group in Phialina.
