Description
The order includes plants that generally grow from a creeping primary stem with reduced leaves, and plants that have spreading to ascending secondary stems which may be pinnately branched. Paraphyllia (tiny branched or stipuliform organs between the leaves) and pseudoparaphyllia are sometimes present on the stems. The leaves may have single or double and sometimes short

and capsules. The double peristome, sometimes reduced, consists of 16 teeth which are papillose on the outer surface, or less often cross-striate at the base, and an endostome with narrow segments and a low basal membrane or none at all. The calyptrae (the protective cap or hood covering the spore case) are cucullate (hooded) and naked, or mitrate and hairy.
