Phaeophyscia kaghanensis Niazi, Nadeem, Afshan & Khalid, sp. nov. is described from Himalayan moist temperate forest in Pakistan. It is characterized by a greyish white to grey thallus, absence of asexual propagules, flat to slightly concave lobes, white medulla, black lower surface, large Physciatype ascospores (24-30×12-17 µm) and absence of secondary substances. In addition, P. microspora Aptroot & Schumm is reported as new to Pakistan, and ITS sequences were generated from this species for the first time.
