中国大陆的梅衣科地衣Ⅴ.球针叶属和球针黄叶属(英文)

Parmeliaceae(Ascomycota) Lichens from China’s Mainland V.The genera Bulbothrix and Relicina

球针叶属Bulbothrix和球针黄叶属Relicina地衣区别于其它梅衣的主要特征是裂片边缘具有膨大似葱头状的缘毛。球针叶属地衣的上表面灰色,含有黑茶渍素(atranorin),而球针黄叶属地衣的上表面为黄绿色含有松萝酸(usnic acid)。经过形态学与化学研究,承认中国大陆有球针叶属地衣5种和球针黄叶属地衣2种。其中戈氏球叶B.goebelii,烟草球针叶B.tabacina,玄球针黄叶R.abstrusa和悉尼球针黄叶R.sydneyensis等4种为中国大陆首次记载。云南球针叶B.yunnana为中国特有种。本文报道的7个种均出现在中国长江以南地区,这与球针叶属和球针黄叶属地衣呈热带,亚热带的世界分布格局相吻合。

Of these Bulbothrix goebelii, B. tabacina, Relicina abstrusa and R. sydneyensis are reported from China＇s mainland for the first time, although they have been previously recorded in Hong Kong and/or Taiwan I. Bulbothrix yunnana is endemic to China.
