新疆黄烛衣科地衣分类学研究初探

Taxonomy of Lichen Family of Candelariaceae in Xinjiang

通过对隶属于新疆黄烛衣科（Candelariaceae）黄烛衣属（Candelaria）和黄茶渍属（Candelariella）的地衣进行分类学研究,初步调查了新疆黄烛衣科地衣物种多样性,使用形态解剖观察和化学检测法鉴定黄烛衣科地衣,报道了黄烛衣属的1个种和黄茶渍属的6个种,其中包括3个新疆新记录种,分别为：帆黄茶渍Candelariella antennaria Rsnen（1939年）、甘肃黄茶渍C.kansuensis H.Magn（1940年）及蛋黄茶渍C.vitellina（Hoffm.）Müll.Arg.（1984年）。对3个新疆新记录种的形态学、解剖学、化学和地理分布进行了描述和讨论,并提供了形态解剖学彩色照片（地衣体、子囊盘、子囊、子囊孢子及侧丝等）和常见种的形态图片。在形态解剖学特征分析的基础上,编制了新疆黄烛衣科地衣分属分种检索表。

The purpose of this study was to investigate the diversity of the lichen family Candelariaceae in Xinjiang. Two genera of Candelariaceae,i. e. Candelaria A. Massal（ 1852） and Candelariella Müll. Arg（ 1894）,were studied,the Candelariaceae species were identified by the morphological anatomic observation. The results of chemical spot tests revealed that one species of Candelaria and six species of Candelariella were found. Among them,Candelariella antennaria Rsnen（ 1939）,C. kansuensis H. Magn（ 1940） and C. vitellina（ Hoffm.） Müll. Arg（ 1984）are the new species for Xinjiang. Newly recorded species were described and discussed according to their morphological,anatomical,chemical and ecological characters. Photos of the thallus,apothecia,asci,ascospores and paraphyses were also offered,and the morphological images of common species were given. Based on the analysis of morphological characteristics,the taxonomic keys to Candelariceae from Xinjiang were presented.
