Ramalina calicaris

Ramalina calicaris is a species of fruticose, bark-dwelling lichen-forming fungus in the family Ramalinaceae. The lichen forms tufted to hanging, greenish-grey shrubby growth anchored by a holdfast at the base, with branches that are often distinctly channelled and strap-shaped, typically 2–3 mm wide and reaching 15–20 cm in length. Its reproductive structures are frequently produced, appearing as pale pink-ochre discs borne at the tips or margins of the branches, often on bends of angled branches with short spur-like projections. The species grows primarily on the branches and twigs of trees and shrubs with nutrient-rich bark, particularly in coastal settings and humid forests. Chemically, the cortex contains usnic acid, while the medulla may contain compounds of the sekikaic acid complex or lack additional substances. The species occurs across Europe (where it is most frequent in western districts), North Africa, Macaronesia, and parts of Asia including China, India, and Thailand. Th......read more on Wikipedia.
