Diphyscium is a genus of mosses in the family Diphysciaceae.Buck, William R. & Bernard Goffinet. 2000. "Morphology and classification of mosses", pages 71-123 in A. Jonathan Shaw & Bernard Goffinet (Eds.), Bryophyte Biology. (Cambridge: Cambridge University Press). {{ISBN|0-521-66097-1}}. Members of this genus are small, perennial plants. The capsule does not elongate much, and remains buried among surrounding leaves.

There are fifteen species of Diphyscium. However, two of these species formerly were placed in the southeast Asian genus Theriotia, and one species, from Chile, formerly was segregated in the monotypic genus Muscoflorschuetzia.{{cite book| last= Schofield | first= Wilfred B. | year=2002 | title=Flora of North America | volume=27 | chapter= Diphysciaceae | pages=162–164 | chapter-url = http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=10281 | isbn=978-0-19-531823-4| publisher= Oxford Univ Pr| location= New York }} In 2003, Magombo proposed reclassifying all fifteen species as belonging to the single genus Diphyscium.{{cite journal| last=Magombo | first=Z.
