LICHENS FROM ARDLEY ISLAND AND FILDES PENINSULA IN KING GEORGE ISLAND, ANTARCTICA Ⅱ.THE GENUS CLADONIA

本文第一作者在参加南极长城站地区科学考察中在乔治王岛菲尔德斯半岛和阿德雷岛采集了大量地衣标本。从形态与化学相结合研究了该地区大型地衣中种类最多的石蕊属，共计12个分类单位，多于国际上有关学者在该地区报道的石蕊属地衣种类。其中，Cl．deformis,Cl．carneola，和Cl．weymouthii等3个种是南设特兰群岛的新记录；Cl.chlorophaea是乔治王岛和阿德雷岛的新记录。Cl．cornuta，Cl．pyxidata和Cl．squamosa等3个种是阿德雷岛的新记录。其余5个分类单位即Cl.borealis,Cl．fimbriata，Cl．gracilissubsp．elongata，Cl．novochlorophaea和Cl．sarmentosa是该地区过去的已知种。记叙和讨论了每个种与邻近种之间的异同，地衣化学和在南极地区的分布。在本研究地区没有发现石蕊科地衣中的其它属。
