摘要
引起唐松草(Thalictrum spp)叶斑点的唐松草单担梗霉菌(Hpalob-asidion thalictri Eriksson)隶属于真菌半知菌亚门,丝孢纲、单担梗霉属(Haplo-basidion)的一种霉菌,主要特征为产生顶端膨大的担子状分生孢子梗,全壁芽殖式产孢细胞及向顶式生长的串生分生孢子。我国尚未有这个菌的记载,为我国半知菌新纪录种。高山唐松草(T.alpinum L.)为该菌的世界寄主新纪录。
Haplobasidion thalictri causing buff-colored leaf spots of Thalictrum alpinum in Xinjiang is a new record species of the genus Haplobasidion for China. It is characterised by simple basidium-shaped conidiophores, holoblastic sporogenous cells and conidia formed acropetally in chains. T. alpinum is a new record of host plant for the fungus.
