摘　　要：蓑藓属(Macromitrium Brid.)是藓类植物中分类最困难的类群之一。先后该属记录946个种,现接受351个种。目前中美洲、亚洲、澳大利亚、新西兰等地区的蓑藓属植物基本完成了分类修订,而南美洲、非洲中部、马达加斯加等地区的蓑藓属植物尚未进行系统的分类修订。蓑藓属的属下分类系统问题众多,先后在该属下建立了10个亚属、20个组和2个亚组,目前接受的有4个亚属和8个组,但是这些类群之间的分类地位和关系仍然不清。鉴于蓑藓属种数多,种间分类问题多,分布广泛,需要开展国际间的合作才能够解决世界蓑藓属的分类修订和系统学研究。The genus Macromitrium is one of the most taxonomically difficult genera in bryophytes. Until now 946 specific names have been reported in Macromitrium, of which 351 have been accepted. The species of Macromitriu~ in many countries and areas have been taxonomically reviewed, which included the Central America, Asia, Australia, New Zealand and the Southern Africa, whereas those in the South America, Central Africa and Madagascarare still poorly understood and are in urgent need of taxonomic revision. Although there are many views and controversies on the classification of Macromitrium, there is not yet a preliminary and widely recognized classification system of the genus Macromitrium. Macromitrium is rich in species and has a worldwide distribution, so we need an international cooperation to conduct a comprehensive taxonomic revision and systematics study on the genus Macromitrium in the world.
