Plants small to robust, tufted or gregarious or cespitose, yellowish green to blackish. Stems erect or repent, simple or forked; central strand present; rhizoids reddish brown, inconspicuous; axillary hairs several per axil, with 2-3 short proximal cells and 5-7 long distal cells. Leaves erect to crispate or circinate when dry, ascending when wet, linear to oblong-lanceolate; margins entire to coarsely serrate, thickened distally; costa single, strong; medial cells isodiametric, in longitudinal files, 1-stratose, or 2-stratose in patches, smooth or slightly papillose. Specialized asexual reproduction rare, by axillary 1-seriate or branched gemmae. Sexual condition autoicous. Perigonia gemmiform, axillary on short naked stalks. Perichaetia terminal but quickly overtopped by innovations; leaves few, short. Seta single or several from a perichaetium, smooth, straight or flexuous. Capsule erect, exserted, brown, ovoid to cylindric, smooth or wrinkled when dry; stomata scarce, proximal on capsule, phaneropore; annulus revoluble; operculum slenderly rostrate; peristome single, teeth 16, short and broad to long and slender, smooth or densely papillose, mostly irregularly divided into 2-3 slender segments beyond the base. Calyptra mostly mitrate, lobed proximally, often deeply so, naked, smooth or plicate. Spores spheric.
