Plants rather robust, jade green to yellowish green or yellowish brown, in loose tufts. Stem cortex in 2–4 layers, hyaline cells thin-walled, without fibrils, sometimes with large pores; central cylinder pale green or yellowish orange. Stem leaves 1.6–1.7 mm × 1.0–1.4 mm, large, ligulate, rounded obtuse, somewhat lacerate at the apex; borders narrow, indistinct; hyaline cells in the upper half broadly rhomboidal, often undivided, without fibrils and pores, sometimes divided, cells in the lower half narrowly rhomboidal, sometimes with the traces of fibrils, with large pores. Branches in fascicles of 4–5, with 2–3 spreading, stout. Branch leaves 2.0–2.3 mm × 1.0–1.2 mm, broadly ovate-lanceolate, concave, strongly squarrose and gradually narrowed to an involute-concave acumen from an erect base; margins involute, blunt and dentate at the apex; hyaline cells densely fibrillose, with small, ringed pores in the upper cells, half-elliptic pores at the opposite ends in the lower cells on the ventral surface, with a few pores at the upper corners in the upper cells, more and more pores at the opposite ends in the lower half on the dorsal surface; inner walls adjacent to green cells sometimes faintly papillose; green cells in cross section triangular to trapezoidal, exposed more broadly on the dorsal surface, also slightly exposed on the ventral surface. Dioicous; antheridial branches green; archegonial branches elongate. Perigonial leaves smaller than vegetative branch leaves. Perichaetia leaves large, broadly ligulate, concave. Spores yellowish, papillose, 22–25 µm in diameter.
