Melanohalea lobulata is a species of foliose lichen in the family Parmeliaceae. Found in the Tibetan Plateau, it was formally described as a new species in 2009 by Fan-Ge Meng and Hai-Ying Wang. The type was collected in Kazilashan, Litang County (Sichuan), at an elevation of 4710m (15,450feet). Here it was found growing on twigs. Its thallus measures 2– in diameter, and has a dark brown upper surface. The elongated-ellipsoid lobules that are developed from (little bumps) distinguish M. lobulata from all the other Melanohalea species.
