摘　　要：采用显微照相的方法描述了七种真藓科植物孢子萌发与原丝体发育特征,结果表明:(1)七种真藓科植物的萌发孢子型均为真藓型(Bryum-type);(2)孢子萌发和原丝体发育特征对真藓科植物系统分类具有重要价值。By miscroscopy,the characters and developmental features of spore germination and protonema development of seven in family Bryaceae mosses were described.The results are as follows：（1） the sporeling type of the seven species belongs to Bryum-type;（2） The features of spore germination and protonema development are important to study on the phylogenetic systematics of Bryaceae.
