Abstract: Tuomeya Harvey (Tuomeya americana (Kützing) 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.
