摘　　要：在对新疆托尔木峰国家级自然保护区、东部昆仑山和阿尔金山国家级自然保护区苔藓植物的调查采集和标本鉴定的基础上,首次报道了锈色红叶藓(Bryoerythrophyllum ferruginascens(Stirt.)Gisc.)和内蒙古红叶藓(B.neimonggolicum X.-L.Bai&C.Feng)在新疆的分布.锈色红叶藓的识别特征为:植物体红褐色,茎中轴发育良好,叶披针形,全缘,叶上部细胞具密疣不透明,基底细胞透明或淡黄色,假根芽胞红棕色,卵球形至不规则形.内蒙古红叶藓识别特征为:植物体矮小,红棕色至褐色,茎中轴分化,叶阔披针形,叶全缘,横切面半圆形.对新疆红叶藓属的两个新记录种的形态特征进行了详细的描述和图示,并初步探讨了该种的生境和地理分布.Based on the investigations and collections of bryophytes in Tumur Peak National Natural Reserve, East of Kunlun Mountain and the Altun Mountain National Natural Reserve in Xinjiang, China, Bryoerythrophyllum ferruginascens(Stirt.) Gisc. and B. neimonggolicum X.-L.Bai & C.Feng were first discovered and reported. The distinctive features of Bryoerythrophyllum ferruginascens(Stirt.) Gisc are as follows: reddish brown plants, well-developed central strand, lanceolate leaves with entire margins, densely papillose cells of the upper part of the leaf and hyaline or yellowish basal cells, and red-brown gemmae which is ovoid to irregular in shape. Besides, B. neimonggolicum X.-L.Bai & C.Feng is recognized by its small size, reddish brown to brown of plants, well-developed central strand, broad-lanceolate leaveswith entire margins, and the cross-section of midleaf which is semiorbicular. In this paper, the taxonomic features, habitat, geographical distribution were preliminary discussed.
