中文摘要：

采用形态解剖、化学、生态类型及地理成分分析等传统分类方法对新疆天山南部巴音布鲁克山区地衣外部形态和内部构造、地衣附属结构、地衣繁殖器官进行观察。利用显色反应法（CT）、微量化学结晶法（MCT）、薄层层析法（TLC）等生物化学方法，鉴定地衣次生代谢产物，发现了1个中国新记录种：乌普萨拉肉疣衣[Ochrolechiaup—saliensis（L．）A．Massal]。文中描述了该新记录种地衣的形态解剖、化学特征和生境，并提供了地衣体、子囊及子囊孢子的彩色图片。

英文摘要：

This research aims at the classification of lichens in Bayinbuluk mount, southern Tianshan Moun- tain, observe the external morphology and internal structure of lichens, lichens subsidiary structure, lichen reproductive organs. By using the traditional classified methods such as lichen anatomical, chemical, ecologi- cal type and geographical composition analysis and biochemical methods such as color reaction（CT）,micro- chemical crystallization（MCT）,thin layer chromatography（TLC）,identified the lichen secondary metabo- lites. As a result,we found a new species：Ochrolechia upsaliensis （L.） A. Massal. new to China. The mor- phological, anatomical, chemical, and ecological descriptions of the species are given. Photos of the thalli, as- ci and ascospores are also presented.
