Ramalina capitata (Ach.) Nyl.

Thallus fruticose with flattened, strap-like lobes, tufted, green-grey, lobe surfaces longitudinally striate with elongated pits and pseudocyphellae, soralia convex to subglobose, abundantly produced from undersides of lobes and short side-lobes at their upcurved tips; apothecia very rare. Generally a coastal species, probably dependent on nutrient enrichment from seabirds, with an old British record from Aberdeenshire and also, very dubiously, from one mountain in the Scottish central highlands, but recently found on gravestones at clusters of sites in Lincolnshire and Yorkshire.
