摘　　要：文中首次报导贵州寒武系黔东统都匀阶"清虚洞组"(或乌训组)宏观藻类,计2属2种:环圈螺旋抚仙藻Fuxianospira gyrata Chen and Zhou,1997和云南中华细丝藻Sinocylindra yunnanensis Chen and Erdtmann,1991,它们是澄江生物群最常见的两类宏观藻类具有澄江生物群宏观藻类的组合特征。"清虚洞组"位于黔东统上部,介于杷榔组和凯里组之间,该组宏观藻类的发现,为寒武纪宏观藻类演化链的完整研究提供了有价值的资料。This paper provides the first report of two species of Cambrian macroalgae, representing two different genera, from the Tsinghsutung Formation （Duyunian Stage, Jianhe county, Guizhou. gyrata Chen and Zhou, Qiandongian Series ） of They are Fuxianospira 1997 and Sinocylindrica yunnanensis Chen and Erdtmann, 1991. These are the two most common species of macroalgae in the Chengjiang biota, so the macroalgal biota of the Tsinghsutung Formation therefore appears to be similar. These fossils provide new information on the palaeobiogeography and evolutionary history of macroalgae in the Cambrian, and on the relationship of the evolution of these algae to their environment.
