A taxonomic revision of 16 of the 21 genera of the large pleurocarpous moss family Hypnaceae is presented for Latin America (Mexico, Caribbean, Central America, and South America).

A total of 35 species are recognized for the entire 16 genera. All taxa were studied taxonomically with each genus and its associated species described in detail. Included in this revision are a description of the family, keys to the genera and species in the Hypnaceae, detailed descriptions of each species with complete information on the known distribution throughout Latin America, habitat information, and nomenclature, and discussions on distinguishing features. Illustrations and distribution maps are provided for many of the species. The following six names are lectotypified: Hypnum micans Sw., Isopterygium cylindricarpum Cardot, Isopterygium lanissimum Mitt., Plagiothecium bolivianum Broth., Plagiothecium restingae var.tenue Müll Hal., and Stereodon distichaceus Mitt.
