Plants large, in dense mats, dark green or olive green, sometimes red. Stems 1-5 cm, rosulate, unbranched or sometimes innovations arising from below terminal rosette, stolons present; rhizoids few to many, at base of stem or arising as macronemata in leaf axils, micronemata absent on leafy stems. Leaves strongly contorted and shrunken when dry, erect-spreading when moist, ovate, obovate, or spathulate, flat, 3-10 mm; base not decurrent; margins revolute proximally, to mid leaf or beyond, or to near apex, strongly serrate from mid leaf to apex, 1-stratose, limbidium of elongate thickened cells, sometimes weak or absent; apex acute, broadly acute, or cuspidate; costa subpercurrent to more often percurrent to short-excurrent, hair-point or apiculus often recurved, , guide cells enlarged, in 2-4 layers; alar cells not differentiated; laminal areolation heterogeneous; proximal laminal cells elongate-rectangular, 3-4:1; medial and distal cells hexagonal, 3-4:1, walls thick, pitted. Specialized asexual reproduction absent. Sexual condition dioicous; perigonia and perichaetia terminal; inner perigonial leaves small, broad, over-arching enlarged disclike pale perigonia with abundant paraphyses; inner perichaetial leaves somewhat differentiated, smaller and narrower than surrounding rosette leaves. Seta 1-8 per perichaetium, straight to slightly flexuose. Capsule inclined to nutant, oblong to cylindric, 3-5 mm; hypophysis differentiated but very short; operculum short-conic; peristome double; exostome brown or yellow-brown proximally, hyaline near apex, teeth lanceolate, acuminate; endostome not adherent to exostome, basal membrane high, segments lanceolate to subulate, perforate, cilia 2-4, nodose to appendiculate. Spores shed singly, 16-24 µm, finely papillose, yellow-brown.
