Plants rather robust, stems and branches slender, stout, yellowish to grayish green, or tinged with light brownish color, in extensive compact cushions. Stem cortex in (2–)3–4 layers, hyaline cells large, thin-walled, with 2–3 large, rounded pores in each cell, without fibrils; central cylinder yellowish. Stem leaves 0.90–1.14 mm × 0.75–0.90 mm, broadly ligulate to oblong-ligulate, broadly rounded-truncate and lacerate-fringed at the apex; borders narrow above, suddenly widened below the middle (ca. 1/3 the leaf width at base); hyaline cells broadly to narrowly rhomboidal from the upper to lower, sometimes divided, without fibrils and pores, with a sieve-like triangular area of resorption at the middle of leaf base. Branches in fascicles of 3–5, with 2–3 spreading, gradually tapering or curved, sometimes short and abruptly tapering, capitulum in 5 radiate rows. Branch leaves 1.0–1.3 mm × 0.50–0.75 mm, imbricate, ovate-lanceolate, erect-spreading when dry; hyaline cells often with pseudofibrillose division, with large, rounded, unringed, central pores on the ventral surface, with small, ringed pores at the corners, rarely with commissural pores in the lower cells on the dorsal surface; green cells in cross section trapezoidal, often exposed on both surfaces, more broadly so on the ventral surface. Dioicous or monoicous; antheridial branches pale brown; perigonial buds globose. Perigonial leaves small, short and broad. Perichaetial leaves large, oblong or ovate-ligulate. Spores yellowish brown, smooth, 30–33 µm in diameter.
