Leaves strongly concave, crowded, appressed or imbricate; lower stem leaves small, bract-like, margins plane, entire or erose-crenulate, costa single or occasionally absent; upper stem and subperichaetial leaves shortly ovate to oblong-ovate or obovate, shortly acuminate, or broadly tapering to an obtuse apex, margins entire below, erose-crenulate to faintly serrulate above, costa single, subpercurrent to shortly excurrent; upper and median cells rectangular, rhomboidal, irregularly quadrate or trapezoidal, incrassate; basal cells rectangular, thin-walled; alar cells not differentiated. Autoicous or paroicous. Perichaetial leaves broadly oblong-ovate or obovate, obtuse to acuminate to short-subulate, costa sometimes ending in a smooth awn. Setae single, short to very short; capsules erect, immersed, emergent or shortly exserted, broadly ellipsoidal to short-cylindric or subglobose to cupulate upon dehiscence; exothecial cells quadrate to trapezoidal or rectangular, moderately thick-walled; stomata present at the base of capsules, superficial; opercula bluntly conic to obliquely short-rostrate; annuli slightly differentiated, in 2–4 rows of quadrate cells, persistent; peristome teeth absent.
