摘　　要：在形态和化学研究的基础上,结合分子生物学研究方法(ITS片段),对中国横断山地区的830号与蓝细菌共生的肺衣属标本进行了分类学研究,共发现3个新种;其中,横断山肺衣L.hengduanensis的主要特征是具粉芽化裂芽,无脊肺衣L.irrugulosa的网脊不明显,以及宽叶肺衣L.latilobulata的裂片顶端宽且钝圆;3个种在ITS系统发育树上分别形成独立小枝。文中提供了中国肺衣属中与蓝细菌共生的物种检索表。Eight hundred and thirty specimens of cyanobacterial Lobaria from Hengduan Mountains were examined morphologically and chemically. Eighteen new nuclear ITS sequences were generated and a phylogeny based on ITS sequences is presented. Three species of Lobaria are described as new to science： L. hengduanensis, L. irrugulosa and L. latilobulata. L. hengduanensis can be recognized by its soredioid isidia; L. irrugulosa is characterized by its indistinct reticulately ridged upper side of the thallus; L. latilobulata differs from other species of the genus in having wide and rounded tips of lobes. These new species formed independent clades on the ITS phylogenetic tree. A key to the cyanobacterial species of Lobaria from China is presented.
