Encalyptales (subclass Bryidae) An order of acrocarpous mosses, in which the leaves are nerved and have a short point at the tip. The capsules are cylindrical and are held erect on long setae; the entire capsule is covered by a distinctive, large calyptra which is often fringed at its lower edge. Mosses of the order are found chiefly on soils rich in lime, e.g. in crevices in limestone walls, chalk banks, limestone screes, etc. There is 1 family, 1 genus (Encalypta), and about 35 species, widely distributed.
