摘要：

本文纪录了淡水红藻串珠藻属Batrachospermum的二个新种。它们采自中国的亚热地区，按其形态特征，它们属于旋转组Section Contorta。采自湖北省的弯形中珠藻B.curvatum与扭曲串珠藻B.tortuosum Kumano相似，但按其轮节、顶毛和受精丝等的形态与后者相区别。采自江西省的弯转串珠藻B.torsivum与赫罗西串珠藻B.hirosei Ratnasabapathy et Kumano相似，但轮节、中轴细胞、节丝和节间丝、果胞枝和受精丝等的大小和形态与后者相区别。

Abstract:

This paper describes two new species of freshwater red algae, Batrachospermum Roth. They belong to the section Contorta on the basis of their morphological characters. B. curvatum, collected from Hubei Province, is similar to B. tortuosum Kumano, but differs from the latter in shape of whorls, terminal hairs and trichogyne. B. torsivum, collected from Jiangxi Province, resembles B. hirosei Ratnasabapathy et Kumano, but differs from the latter in shape and size of whorls, axial cells, cells of the nodal and internodal filaments, carpogonial branches and trichogyne.
