Species: Flavoparmelia soredians
Photos: On urban trees. Co. Cork, SW Ireland.
Very similar to F. caperata but has a smaller thallus narrower and more adpressed lobes. Soredia is powdery rather than granular. Apothecia are rare but usually contain mature spores.
Occurs on well-lit, often dusty trees, fences, roofs, rocks. Range seems to be increasing as pollution levels drop.
