Images of British Lichens
Ramalina canariensis J.Steiner
Thallus fruticose, tufted, with ragged, flattened branches that broaden from the base and are often hollow and partly inflated, branch surfaces smoothly wrinkled, lacking pseudocyphellae, soredia produced from lateral or subterminal soralia that are splits along the margin, and also in inflated, ruptured, terminal vesicles; apothecia laminal or marginal but very rare. Widespread but local on trunks, rocks and walls, much more common in south and south-west England and Wales. Not, on the whole, an elegant species.
