Pilotrichaceae is a family of pleurocarpous mosses in Hookeriales. It includes 20 genera.^[1] It is primarily tropical and epiphytic or epiphyllous.^[2]

Description

Members of the family are characterized by a double costa, sometimes with hyalodermis, and no alar differentiation. Leaves are usually complanate and may by asymmetrical along the dorsal/ventral axis. Leaf margins are dentate to serrate, bordered or not, and often reduced. Laminal cells are isodiametric to linear and smooth to papillose. The sporophyte seta is long, but many other characters vary genus to genus.^[3]
