Usnea cornuta is a fruticose lichen in the family Parmeliaceae, assessed as Near Threatened (NT). It forms shrubby, branching thalli that hang from tree branches and twigs, typically in humid forest environments. Like all Usnea species, it is highly sensitive to air pollution, particularly sulfur dioxide, making it a useful bioindicator of air quality.
