Usnea glabrata is a species of beard lichen in the family Parmeliaceae. It was first described as a variety of Usnea plicata by Erik Acharius. Finnish lichenologist Edvard August Vainio transferred it to the genus Usnea in 1915.^[2] The lichen grows on bark and is widespread throughout Europe, although it is probably locally extinct in a few locations. It is characterized by small shrubby thallus, constriction of secondary branches at their base, presence of large soralia, and the absence of both papillae and isidia.^[3]
