Plants robust, soft, glossy, in loose mats. Stems extensively creeping, with few, remote and irregular branches; branches long and somewhat regularly pinnately further branched with short branchlets; branchlets round, blunt at tips, frequently bent down; rhizoids loose. Leaves imbricate-appressed when dry, nearly erect-spreading when moist, oblong-ovate, concave, slightly decurrent at base, abruptly narrowed to a filiform acumen; margins plane or only involute at apex, entire or weakly toothed at tip; costae double, very short or absent; leaf cells narrowly linear, smooth; basal cells broader and shorter, brownish yellow; alar cells in several rows, yellowish, quadrate, thick-walled, somewhat hyaline, forming a large, slightly concave, well-differentiated alar region. Autoicous. Inner perichaetial leaves erect, ovate-lanceolate, gradually becoming a long filiform acumen, nearly entire; costae none. Setae slender, reddish, smooth, often twisted when dry; capsules erect, cylindrical, apophyses short, thin-walled, the mouth not constricted when dry; opercula conic, bluntly tipped; annuli narrow, persistent; peristome double; exostome teeth broadly lanceolate, blunt at tips, yellowish, smooth below, inner surface densely trabeculate; endostome segments hyaline, broad and short, finely papillose, blunt at tips, keeled; basal membrane low, cilia absent.
