Farinose Cartilage Lichen

Ramalina farinacea is a species of fruticose lichen in the family Ramalinaceae. It appears as small, shrub-like tufts typically 3–6 cm (1.2–2.4 in) long that hang from tree branches and trunks, particularly in woodland areas and on isolated trees. Distinguished by its flattened, yellow-green to grey-green branches with powdery white spots along the edges, this lichen is widespread throughout temperate regions, especially in coastal areas with oceanic climates. First scientifically described by Carl Linnaeus in 1753 and later reclassified by Erik Acharius in 1810, it is remarkably tolerant of air pollution compared to other lichens, which enables it to thrive in environments where similar species cannot survive. While primarily reproducing through the dispersal of powdery particles called soredia, it occasionally produces disc-shaped fruiting bodies (apothecia) along its branches.
