Bryum is a genus of mosses in the family Bryaceae. It was considered the largest genus of mosses, in terms of the number of species (over 1000), until it was split into three separate genera in a 2005 publication.[1] As of 2013, the classification of both Bryum and the family Bryaceae to which it belongs underwent significant changes based on DNA studies.[2]

History
The genus was described by Johann Hedwig in 1801, with the name being derived from the Greek word for moss.[4][3]
Botanist John R. Spence published a reclassification of the genus in 2005. The genus Ptychostomum was reinstated, while the genera Leptostomopsis, and Plagiobryoides were created.[1] The genera Gemmabryum, Imbribryum, and Rosulabryum were later published to further divide Bryum.[5]
