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 , Litang County (Sichuan), at an altitude of 4,710 m (15,450 ft). Here it was found growing on twigs. Its thallus measures 2–13 cm (0.8–5.1 in) in diameter, and has a dark brown upper surface. The elongated-ellipsoid lobules that are developed from papillae (little bumps) distinguish M. lobulata from all the other Melanohalea species.
