【摘要】 茶渍属地衣广泛分布于新疆北部.其基本特征为几乎都具有特久的子囊盘,子囊盘茶渍型.绝大多数茶渍属地衣适应于生活在干旱半干旱地区.它们对环境的适应性能力强.我们在进行分类的过程中,采用微量化学结晶法(MCT),薄层色谱法(TLC)等方法检测地衣物质,通过观察子囊盘结构、颜色和对地衣次生产物的分析,并对采自于新疆阿勒泰山哈纳斯自然保护区和天山天池所采集的茶渍属(Lecanora Ach.in Luyken) 300余号标本进行了整理及分类,初步定名新疆新记录地衣3种(Lecanora cenisia Ach , Lecanora crenulata,Lecanora intricata) ,本文对此三种新疆新记录地衣进行详细的描述并提供了三种新疆新记录地衣的彩色图片.所引用标本均保存于新疆大学资源植物标本室.更多还原

【Abstract】 The genus $Lecanora$ belongs to the crustose lichens and is widely distributed in the North part of the Xinjiang. In the Genus $Lecanora$, almost all of the species have persistent lecanorine type apothecia. Most of them exist in arid or semiarid regions. As part of a revision of this genus, extensive collections were made in the Hanas Natural Reserve , and we have found three new records to Xinjiang: $Lecanora cenisia Ach$ , $Lecanora crenulata$ (Schaer)Heu in Bull and $Lecanora intricate$ Ach.Llenas. The Lichen products of each species was detected by using color test, TLC and also MCT to some species. The descriptions of each species with comments and color photographs are provided.In this revision we have studied about 300 specimens, and all of them are housed in the herbarium of the College of Life Science and Technology of Xinjiang University in Urumqi.更多还原
