秦岭太白山地区黑蜈蚣衣属地衣的研究

STUDIES ON THE LICHEN GENUS PHEAOPHYSCIA FROM TAIBAI,QINLING MOUNTAINS IN CENTRAL CHINA

对采自秦岭太白山地区黑蜈蚣衣属地衣130份标本,从形态、解剖、化学及地理分布方面作了全面分析.共报道了本地区黑蜈蚣衣属地衣15种,占中国本属地衣的71.4%,其中西北地区新记录3种,秦岭太白山地区新记录6种;并将其划分为3个地理成分:世界广布1种、温带成分(包括3个分布型)12种、中国特有成分1种,另有1种难以确定其成分.

Studies on the lichen genus Phaeophyscia from Taibai, Qinling Mountains in central China are performed using the methods of morphology, anatomy, chemistry and geography on the basis of identification of about 130 specimens. Fifteen species are reported in the present paper, including 3 taxa new to Northwestern China, and 6 taxa new to Taibai, Qinling Mountains. The geographical elements of them are classified as follows： cosmopolitan element （ 1 species）, temperate element with 3 distributional patterns（ 12 species）, species endemic to China（ 1 species）. Geographical element for 1 species is difficult to be determined.
