Maritime Sunburst Lichen (Xanthoria parietina) - found in sunny, exposed places that are rich in nitrogen. Xanthoria parietina forms a conspicuous yellow band on sea cliffs where there are plenty of seabirds to provide the nitrogen that it loves. It is also found in other nitrogen rich habitat such as on trees and farm rooves and man-made substrates inland where the atmospheric nitrogen levels are high.
