【摘要】 依据一份采自马头山自然保护区的标本,报道白藓为江西新记录,并对该种的配子体形态特征作了详细描述和绘图.同时白藓科、白藓属也是江西首次记录.白藓与中国广布种鳞叶藓特征相似,区别在于后者羽状分枝、有假鳞毛、叶具明显双中肋和叶上部边缘有细锯齿.植物体小,罕见及孢子体不发育等表明江西马头山自然保护区的常绿阔叶林非白藓的适生生态环境.更多还原

【Abstract】 Based on the identification of one specimen from Matoushan Nature Reserve,Leucomium strumosum was reported from Jiangxi Province,China for the first time.The family Leucomiaceae and genus Leucomium Mitt.were also new to this province.A detailed description of gemetophytic characteristics and illustrations of this species were provided.L.strumosum is morphologically closest to Vesicularia reticulata which is common in China,but the latter is densely pinnately branched,has pseudoparaphyllia,as well as a distinct double costa and clearly serrulate upper margins in the leaves which differs from L.strumosum.Some features,such as the small and rare plants,absence of sporophytes,suggested that the evergreen broad-leaved forests in Matoushan do not provide an optimally ecological environment for L.strumosum.更多还原
