Ramalina subfarinacea (images of British lichens)

Thallus erect, tufted, much branched, resembling R. farinacea but differing in the spreading, patch-forming holdfast, equally abundant but less well delimited marginal soralia with granular soredia, often more yellowish colour, and habitat; apothecia evidently rare. Widespread around the coast on rocks and cliffs, apparently requiring more sheltered sites than R. siliquosa, also sometimes inland but perhaps over-reported.
