Two new records of Pertusaria (lichenized ascomycetes) from China
中国鸡皮衣属二新记录种

1 INTRODUCTION Pertusaria is a fairly large genus of Pertusariaceae with around 170 species recognized(Kirk et al.2001).The genus is characterized by the verrucose thallus,and the large spores(often longer than 30μm)with a conspicuously thick wall(more than 2.5μm thick).Both morphology and chemistry are essential for identifying species in this genus(Oshio 1968; Dibben 1980; Archer 1991,1997;Lumbsch et al.1999).Studies of the Chinese Pertusaria have been extensively developed with 45taxa accepted to data(Zhao et al.2004).A considerable portion of these taxa are difficult to be distinguished without chemical data which,however,have been detected for only a handful of species (Yu et al.1999; Zhao et al.2004).
