Plants simple to sparingly branched by innovations, light olive green. Stems 2-3 cm, slender and wiry, erect. Leaves 3-5 mm, ovate-lanceolate, with a sub-sheathing base, ± erect-appressed when dry, somewhat spreading when moist, channeled distally, with lamellae on both surfaces; costa percurrent, ending in a short apiculus; margins narrowly reflexed, denticulate to distinctly serrate in distal 3/4; abaxial lamellae well-developed, on the back of both costa and lamina, the lamina with 3-4 regularly spaced lamellae on either side of the costa, 1-3 cells high, serrate like the leaf margins; adaxial lamellae 5-7, undulate, 5-9 cells high, confined to the midrib, undulate, serrate like the leaf margins; cells of leaf base short-rectangular; median cells of lamina rounded-quadrate, 12.5-20 µm wide, in ± regular longitudinal rows; perigonial leaves broadly triangular-ovate, forming a large, conspicuous rosette; perichaetial leaves larger and broader than the vegetative leaves, erect when dry, subsquarrose when moist. Seta 3-4 cm, reddish yellow, wiry, often strongly twisted in distal half when dry. Capsule 4-5 mm, cylindric, rather pale, terete or with 4 or more longitudinal ridges; hypophysis with numerous superficial stomata; peristome teeth 32, pale, double. Spores 10.5-13 µm.
