Teloschistes flavicans (images of British lichens)

Fruticose, pale to golden yellow or orange, much branched, tufted to pendant, with tubercle-like soralia; apothecia not recently seen in Britain. Formerly widespread in the south on trees and rocks and in coastal turf and heath, but evidently highly pollution sensitive and now restricted to just a few coastal sites in south-west England and western Wales, especially on islands and in localities subject to sea-mist.
British Red Data Book species: vulnerable; scheduled protected species, Wildlife and Countryside Act 1981.
