Glypholecia scabra is characterized by its squamulose thallus, abundant and compound apothecia, and umbilicate lower surface, as shown in Fig. 2A-F, J-L . In the Qinghai-Tibetan Plateau, these specimens have an umbilicus at the center of the lower surface, formed by fasciculate white rhizines, which are single or branched, dense or loose. It has a global distribution (see citations above). Within China it has been reported from Gansu ( Magnusson 1940; Cao and Wei 2009), Xinjiang ( Wang 1985; Abbas et al. 1993; Abbas and Wu 1994 1998), Ningxia ( Liu and Wei 2013) and Xizang ( Wei and Jiang 1986) provinces. Delimiting species boundaries can be complicated by the potential role of the environment in shaping morphology. Our phylogenetic study showed that a specimen previously collected and reported from Gansu (GenBank number: FJ919810 ) did not belong to the genus Glypholecia , but should rather be placed within Acarospora . We also report a new record for G. scabra in Neimenggu province, northern China. For further synonyms and detailed descriptions of G. scabra , see Thomson (1979) and Ryan (2002) .
