Gemmabryum is a genus of moss in the family Bryaceae.[1] It was separated from the genera Bryum and Brachymenium in 2005. It has been argued that the correct name for the genus is Osculatia.
The genus Gemmabryum was first described by J. R. Spence and H. P. Ramsay in 2005. Species previously placed in three sections of the genus Bryum and one section of the genus Brachymenium were transferred to the new genus,[2] which is accepted by the World Flora Online database as of March 2024[update].[1] Other sources retain the genus Bryum.[3] In 2018, it was argued that the genus name Osculatia De Not. had priority for this segregate of Bryum and Brachymenium.[4]
