Discussion: The genera in this family are gametophytically diverse, but all possess the same distinctive "double" peristome which consists of an "endostome" (with a lightly thickened ventral surface and strongly thickened dorsal trabeculae) and an "exostome" that either adheres to the margins of the teeth as a thin membrane or occurs as a prostome at the base of the teeth (Edwards 1979).
