A family of acrocarpous mosses of the order <em>Bryales</em>, typified by the genus <em>Mnium</em>, and distinguished from the <em>Bryaccæ</em>, to which it was formerly referred, by the club-shaped (instead of filiform) paraphyses of the male organs, and by the hexagonal (not rhombic) parenchymatous cells of the upper surface of the leaves. There are 4 genera and 79 species, of which latter 72 belong to the genus <em>Mnium.</em> They grow in moist, shady places, on the ground, on the bark of trees, or on rocks, and are found in nearly all parts of the world, but chiefly in temperate regions.
