中国新记录属——绿叠球藻属及其系统位置

A Newly Recorded Genus in China——Chlorokybus,and Its Systematic Position

在对上海市树附生藻类的调查中,发现了1个中国新记录属——绿叠球藻属(Chlorokybus)。对该属1个新记录种绿叠球藻(Chlorokybus atmophyticus)的主要形态学特征进行了详细描述,对其系统位置讨论结果认为,绿叠球藻是一个比较特殊的藻类,在陆生植物演化上具有特殊的地位,支持将其作为一个独立的目——绿叠球藻目(Chlorokybales)处理。

In the survey of epiphytic algae on the tree in Shanghai, Chlorokybus, a newly recorded genus in China was observed. The main morphological characters of the newly recorded species of it （Chlorokybus atmophyticus） was described in detail. Based on the discussion of its systematic position,we found that C. atmophyticus was a special algae which played a significant role in the evolution of land plants. We suggest that it should be treated as a separate order-Chlorokybales.
