Description:Genus Description - Plants small to fairly robust, dark-green to glaucous, and occasionally yellowish-red, in loose or dense tufts, erect, simple or sparsely branched. Axillary hairs of 3 or more cells, the terminal cell elongate, thick- or thin-walled, the intercalary cells hyaline or with cross-walls pigmented, the basal cell(s) sometimes brown. Leaves erect-appressed to spreading or circinatecurved, occasionally flexuose, slenderly lance-subulate from a ± sheathing, non-plicate base, the tips often brittle; margins serrulate above, with teeth single or paired; costa strong, prominent at back, disappearing below the apex to excurrent; upper cells short- to long-rectangular, papillose at the ends; basal cells longer, often laxer, usually smooth; alar cells not distinctly differentiated or rarely quadrate in several rows. Perichaetial leaves similar to stem leaves (but often less papillose), rarely distinctly differentiated and ending in long, capillary points. Setae 4-25 mm long, straight or curved, smooth; capsules erect, inclined, or cernuous, ± asymmetric, subglobose to short-ovoid, furrowed when dry; operculum convex, with a low, blunt point; peristome double, single, or absent, the exostome teeth 16, frequently cleft above the middle, papillose or smooth; endostome consisting of a basal membrane, keeled segments, sometimes lacking, and cilia none or poorly developed. Spores reniform to subspherical, verruculose.
