Abstract:
In this study, the diversity of Pyxine Fr. in China was assessed based on morphological and chemical traits and molecular data are inferred from ITS and mtSSU sequences. Nineteen species were recognised, including three that are new to science (i.e. P.flavicans M. X. Yang & amp; Li S. Wang, P.hengduanensis M. X. Yang & amp; Li S. Wang and P.yunnanensis M. X. Yang & amp; Li S. Wang) and three records new to China were found (i.e. P.cognata Stirt., P.himalayensis Awas. and P.minuta Vain.). Pyxineyunnanensis is diagnosed by the small size of the apothecia, a white medulla of the stipe and the presence of lichexanthone. Pyxineflavicans is characterised by broad lobes, a pale yellow medulla of the stipe and the presence of atranorin. Pyxinehengduanensis can be distinguished by its pale yellow medulla, marginal labriform soralia and the absence of atranorin. Detailed descriptions of each new species are presented, along with a key to the known species of Pyxine in China.
