Belongs within: Bryidae.
Contains: Webera subgenus Eu-Webera, Bryum section Eu-Bryum, Bryum section Leucodontium.
The Bryaceae are a large family of mosses found world-wide. Members of the family often have erect stems and form short turfs. The Bryaceae has recently been treated in a more restricted sense than previously, with the removal of groups such as Pohlia and Mielichhoferia to other families. Members of the type genus Bryum are densely tufted mosses with more or less ovate leaves, that usually bear pendulous capsules on a long seta (Dixon 1924).
Characters (from Smith & Smith 2004): Dioicous, autoicous or synoicous. Usually erect tufted or turf-forming plants. Leaves broadly ovate to lanceolate, often forming comal tuft, frequently bordered with narrow elongate cells; costa well-developed, often excurrent; cells thin-walled, frequently rhomboid-hexagonal, smooth, pellucid. Setae long; capsules inclined to pendulous, ovoid to cylindrical, with differentiated neck; peristome usually double, inner ring often with well-developed basal membrane, cilia present or not; calyptrae cucullate.
