Greenish on Betula leaf
Juuso Äikäs, 16-10-2020 15:02
These yellowish-greenish little ascos were growing on a fallen leaf of Betula sp. The paraphyses and hairs had nice greenish VBs that disappeared with the addition of KOH. IKI+, croziers+. The spores measured 14.3-17.5 x 1.8-2.6 microns.

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.
