中国砖孢发属地衣研究

THE LICHEN GENUS OROPOGON FROM CHINA

简短回顾了砖孢发属地衣研究概况。在已知的8种亚洲砖孢发属地衣中,中国有七种,其中两种为台湾特有。根据150余份标本的形态与化学特征,承认中国大陆砖孢发属地衣5种,指出了个别异名,发现亚洲砖孢发(Okpogon asiaticus)存在两个化学型,提供了中国5种砖孢发地衣分布的新资料。研究结果表明,5种砖孢发地衣集中分布于我国云南、四川和西藏东部。作者认为中国西南地区是砖孢发属地衣在亚洲的一个分布中心。

A short review about the studies on the genus Oropogon is given, and 5 species of Oropogon from China's Mainland are reported. They are O. asiaticus, O. formosanus, O, orientalis, O. secalonicus, and O. yunnanensis. O. asiaticus from China includes two chemotypes: chemotype. 1 containing psoromic acid and chemotype II containing psoromic & placodiolic acids. These 5 species are distributed mainly in southwest China: Yunnan, and Sichuan, East Xizang (Tibet).
