Plants small, green above, light-brown below, generally about 2 mm high. Leaves 1.5-2.5 mm long, narrowly long-lanceolate to oblong-lanceolate, sharply acute, mucronate, not much differentiated at base; margins incurved to tightly involute; costa with epidermal cells quadrate and papillose on the ventral surface, elongate and papillose on the dorsal; upper cells in longitudinal rows, subquadrate to hexagonal, 7-9 µm wide, bulging and bearing 4-6 bifid papillae on both surfaces (occasionally fused together in a capitate cluster); basal cells differentiated across the leaf, mostly thin-walled, up to 25 µm wide and 2-3:1. Autoicous. Setae 4-6 mm long, yellow-brown, twisted clockwise; capsules 1-1.4 mm long, oval, yellow- to red-brown; exothecial cells in 1-2(-4) layers, subquadrate to short-rectangular, ca. 30 µm wide and 1-3:1, rather thin-walled; annulus of 2-3 rows of cells; operculum 0.5-0.8 mm long, rostrate; peristome teeth none, few and rudimentary, or 16 oblong to long-triangular and irregularly cleft, straight, yellow to orange, papillose to low-spiculose teeth with as many as 6 joints and up to 125 µm long (occasionally falling with the operculum). Spores (15-)18-20(-23) µm, yellow to brown,papillose.
