Fructicose lichen. Dense and highly branched Ramalina that is typically erect reaching a height of between 2 cm and 3 cm. It has green-grey to grey thalli; the apothecia are white and deep cupped (concave) when young and are flat to convex when mature. The branches are flat and covered with many tiny holes (fenestra) and striations.
Ramalina fastigiata is very sensitive to air pollution. Grows in tufts on tree trunks and twigs, usually on the side of the tree exposed to strong sunlight. It likes nutrient rich bark and hedges (near farms, for example). Rarely occurs on rocks. Spotted on the bark of an oak tree
