Placocarpus schaereri is a species of saxicolous (rock-dwelling), areolate, and crustose lichen in the family Verrucariaceae. Found in Europe, it is the type species of genus Placocarpus. The lichen was first described scientifically in 1831 by Elias Magnus Fries, who called it Parmelia schaereri. The species epithet honours Swiss pastor and lichenologist Ludwig Schaerer.[2] Othmar Breuss transferred it to the newly reinstated genus Placocarpus in 1985.[3]
