摘　　要：报道了中国淡水红藻一个新记录属——托氏藻属Tuomeya Harvey。标本采于江苏徐州。该属以植物体软骨质, 多层细胞紧密排列组成坚固的皮层, 果胞枝弯曲等特征, 区别于串珠藻科Batrachospermaceae的其他属。除对此种藻类的形态作详细描述外, 还通过rbcL序列比较分析其与北美地区样本的地理差异。该属先前在加拿大、美国和南非有过报道。Tuomeya Harvey （Tuomeya americana （Küzing） Papenfuss） is reported as new record to China. The specimens were collected from Xuzhou in Jiangsu, East China. This genus is characterized by a cartilaginous thallus and solid cortex, which is composed of numerous compact cortical cells. Its carpogonial branches are twisted. In addition to describing the morphological and reproductive structures of T. americana in detail, we also use rbcL gene sequences aligned with the previously published sequences of T. americana from North America. Tuomeya includes only one species, which was previously known from North America and South Africa.
