(subclass Bryidae)

An order of small, sometimes minute, acrocarpous mosses. The leaves and shoots are often poorly developed, and the capsule is disproportionately large; in some species there are no leaves and the branched, filamentous protonema is persistent. They are found on acid soil on moorlands and in woods, and on soil-covered rocks in mountainous regions. (This characteristic group of mosses is sometimes elevated to subclass level: Buxbaumiideae.)
