The Hookeriales is an order of mosses found primarily in tropical and subtropical parts of the world. They are distinguished from other pleurocarpous mosses by having undifferentiated alar cells. Members of the Hookeriales can be divided between the Ptychomniineae, with furrowed capsules, and the Hookeriineae with smooth capsules.
Characters (from Smith 2004): Pleurocarpous. Leaves often complanate and often asymmetrical, sometimes with border of elongate cells; costa single or double, long or short or absent; alar cells not differentiated. Setae often rough; capsules exserted, erect, inclined or horizontal; peristome double, exostome teeth long, tapering, often furrowed, usually with thickened lamellae on inner face, basal membrane of endostome high, cilia absent; calyptrae conical, often hairy or fringed.
