Usnea scabrida is a foliose lichen that grows from holdfasts on trees.[1][2] It occurs in southwest Western Australia.[3] It is a very pale grayish-yellowish green, slender, pendant, branching from the base, unequally branching, and shrubby.[3] The cortex contains usnic acid, and the medulla contains scabrosins.[4] The lichen was described as a new species in 1844 by English botanist Thomas Taylor.[5]
