DescriptionA shrubby, yellow-grey to greenish grey lichen between 2 -7 cm long. The thallus is composed of erect or slightly pendant lobes, arising from the base, little divided, often scimitar shaped but very variable. Lobes may be glossy, or with granular outgrowths (warts) and wrinkled. The lobes are 2-9 mm wide with white spots towards the tips but not normally blackened at the base. The thallus often bears pale fawn coloured fruiting bodies, usually on short stalks. The thallus is hard and brittle when dry.Ramalina siliquosa is eaten by sheep in Shetland and North Wales (Dobson, 2000).
