Plants medium-sized, up to 6 cm long, slightly rigid, dark green, lightly brownish green when old, in loose flat patches. Stems usually bipinnately branched, in cross section outer cortical layer consisting of 3–4 layers of small, thick-walled cells, becoming larger cells, but rather thick-walled in the inner cortical layer; central strand consisting of 5–6 small cells; paraphyllia dense, filamentous, forked, papillose; branches ca. 0.5 cm long. Stem leaves remote, slightly plicate, with ovate-triangular or ovate-cordate bases, suddenly narrowed to piliferous apices, 1.0–1.5 mm long; costa vanishing below leaf apex; margins serrate; branch leaves ovate-triangular, younger leaves ovate to widely ovate, with narrowly obtuse apices, ca. 0.2–0.3 mm long; leaf cells rounded hexagonal, oblong, median cells 10–15 µm long, rather thick-walled, with single, sharp papilla on dorsal surfaces. Dioicous. Inner perichaetial leaves gradually narrowed from oblong bases to lanceolate, piliferous apices, margins long ciliate. Setae densely papillose, up to 3 cm long; capsules reddish brown, oblong ovoid; opercula shortly beaked; exostome teeth lightly yellowish to lightly red, densely transversely striate, hyaline at apex, papillose; endostome segments lightly yellowish; basal membrane ca. 1/2 the height of segments, papillose; cilia 3–4, nodulose. Spores nearly smooth, 12–15 µm in diameter.
