摘　　要：以采自新疆地区的地衣标本为试验材料,通过观察和研究该地衣形态解剖特征、次生代谢产物以及构建核糖体DNA内转录间隔区(internal transcribed spacer,ITS)系统发育树,研究鉴定该地衣标本为蜈蚣衣科(Physciaceae)1个中国新记录属:金奥克衣属[Oxnerella(S.Y.Kondr.,Lo″k?s&Hur)]及中国新记录种双裂金奥克衣[O.safavidiorum(S.Y.Kondr.,Zarei-Darki,Lo″k?s&Hur)],该种含有柔扁枝衣酸,文中提供了该种形态解剖图,并讨论了其与相似物种的关系。In this paper,we used morphology,anatomy,lichen chemistry and phylogeny methods to study the specimens collected from Xinjiang,China.Divarictic acid was detected from some collections by Color test(CT),thin layer chromatography(TLC)and high Performance Liquid Chromatography(HPLC).Morphological characters,secondary metabolites,and phylogenetic tree of ITS of the specimens showed that some specimens should be identified as Oxnerella safavidiorum.Therefore,the genus Oxnerella with species O.safavidiorum are reported for the first time from China.Descriptions with photos of the thallus,apothecia,asci and ascospores are provided based on Chinese collections.In addition,the relationships of the species and its related species are discussed.
