The genus Bryonora was segregated from Lecanora on the basis of the morphology of the apothecia. It consists of c. 15 species occurring on acid substrata (rocks, soil, plant debris, mosses), mostly above treeline, and has the highest diversity in the mountains of Central Asia. The molecular analysis by Svensson & al. (2022) confirmed the position of the genus in the Lecanoraceae, while finding no support for treating Bryodina Hafellner as a genus separate from Bryonora.
