Stem leaves remote, suddenly narrowed from an ovate or triangular base to a lanceolate or narrowly lanceolate apex, 0.8–1.0 mm × ca. 0.6 mm; margins revolute or recurved, serrate or cellulose; costa single, consisting of 3–4 rows of narrow and thick-walled cells, papillose on back; leaf cells 7.5–10.0 µm, hexagonal to irregularly rectangular, with single acute or 2–4 fine papillae, walls equally thickened; branch leaves dense, appressed when dry, widely cordate to ovate-triangular, with a short, obtuse apex, rarely acute; marginal cells projected, round-toothed, finely papillose; costa reaching 2/3–4/5 the leaf length, papillose on back. Autoicous. Female inflorescences on stems, with 7–8 perichaetial leaves; inner perichaetial leaves oblong-ovate; costa broad, excurrent into a long awn; margins remotely crenulated, sometimes with 8–10 single celled, hyaline, cilia above. Setae ca. 1.0–1.5 cm long, lightly brownish, reddish when old, densely granulate; capsules ovoid to shortly cylindrical, ca. 0.5–1.2 mm long, horizontal or inclined; opercula 1 mm long; peristome teeth well developed, cilia 1–3, isolated or connected, sometimes rudimentary.
