Plants small to medium-sized, gregarious or caespitose. Stems 2-6(-10) mm, erect, simple except for a basal antheridial branch. Leaves crispate to contorted when dry, erect to spreading when moist, oblong-ovate to broadly obovate, concave, 1.5-3(-10) mm; apices acute to acuminate; margins entire to serrate distally; costa single, subpercurrent to excurrent; proximal laminal cells elongate-rectangular, distal cells rhombic-hexagonal to rectangular. Sexual condition autoicous; antheridial branches 1-2, basal, perigonial paraphyses clavate with an enlarged inflated cell. Seta erect to strongly curved or twisted, (3-)7-20(-80) mm. Capsule stegocarpous, usually inclined to pendent, exserted, asymmetric and usually curved, pyriform, 1.5-3 mm, often sulcate or plicate when dry and empty; exothecial cells oblong-hexagonal to linear, walls incrassate especially so on inner tangential wall; stomata immersed; annulus large and revoluble or not differentiated; operculum convex to weakly conic, usually oblique to the axis of the capsule, cells in obliquely radial rows; peristome double, teeth well developed, oblique, lance-acuminate, papillose-striate, often strongly trabeculate, frequently appendiculate at the tips and fusing with a latticed disk, endostome segments opposite the teeth, 1/6 or more the length of the teeth, papillose or weakly papillose-striate with a basal membrane, cilia absent. Calyptra cucullate, often long-rostrate, large, usually smooth. Spores spherical, smooth or papillose to baccate-insulate.
