Slender plants in dense, dull, deep-green to yellow-brown tufts, somewhat radiculose at base. Stems erect-flexuose, irregularly forked, densely foliate. Leaves dimorphous, appearing to be distichous but actually strongly complanate though spirally inserted, with small and inconspicuous, erect, remote, ovate-lanceolate, acuminate leaves on 2 sides of the stem and larger, erect-spreading, keeled-concave, elliptic, apiculate to shortly awned leaves crowded together in 2 apparent rows; margins erect, irregularly serrate; costa single, strong, yellow, shortly excurrent; cells small and subquadrate throughout, bluntly pluripapillose. Dioicous. Perichaetial buds near the base of the stem, with bracts sheathing and erect-subulate. Setae elongate, slender, flexuose, red-yellow; capsules erect and symmetric or somewhat curved, ellipsoidal-cylindric, chestnut-brown, with 8 darkened bands of cells forming ribs, contracted below the mouth and furrowed when dry; annulus none; operculum obliquely long-rostrate; peristome teeth 16, inserted somewhat below the mouth and joined at base, slenderly lance-acuminate, longitudinally striate, yellow. Spores small, spherical, very finely papillose-roughened. Calyptrae cucullate, smooth, naked.
