Similar to Hypotrachyna revoluta, but with thallus lobes that tend to be more robust, slightly larger and more recurved, and soredia that are coarsely pustular rather than evenly farinose. The rhizines tend also to be darker brown than in H. revoluta.
Assessed by Woods & Coppins as of Least Concern.
Scattered throughout Great Britain; likely to be more widely distributed, due to historical confusion with H. revoluta. BLS map here.
On bark of broadleaved trees.
