A taxonomic study of the genus Porpidia in western China revealed two species hithertounknown to science, Porpidia squamosa and P. shangrila, along with three new records for the country:P. flavicunda, P. soredizodes and P. thomsonii. Detailed taxonomic descriptions, ecological and chemicalcharacters, and illustrations are provided for the new taxa, and brief taxonomic descriptions providedfor the newly reported taxa. A key to all known Chinese Porpidia species is also provided.Key words: key, saxicolous lichens, taxonomyAccepted for publication 14 April 2012 IntroductionPorpidia Ko¨rb., one of the largest genera seg-regatedfrom Lecidea (Hertel1975),hasbeenwell studied in different parts of the world(Hertel 1975; Gowan 1989; Fryday 2005).Previously only seven species have been re-ported from China (Wei 1991), with mostbeing discovered by Hertel (1977). SinceHertel’s work no further research has beencarried out on the genus in China.Ourstudy wasmainly focused onthewest-ern part of China, which covers nine pro-vinces, Gansu, Guizhou, Ningxia, Qinghai,Shaanxi, Sichuan, Tibet, Yunnan, and Xin-jiang, and one municipality, Chongqing. Itis a region of sunken basins, rolling plateaux,and towering massifs at altitudes varyingfrom less than 500 m to more than 4000 m.The areaincludesfive mainmountainranges:Tianshan, Kunlun, Qilian, Hengduan andHimalaya Mountains; the highest tablelandon Earth is also located in this region.Porpidia specimens were mainly collectedfrom the mountainous regions at an altitudeof more than 1000 m. The first two authorscarried out the field survey, in the most partfrom the mountainous region in south-western China. We also identified many pre-viously unexamined specimens of Porpidialodged in various herbaria in China [HMAS,KUN, SDNU]; these specimens were col-lected from the western part of China. Ourstudies led to the discovery of two new spe-cies, described here in detail, and three newrecords for the Chinese lichen mycota.Materials and Methods
