Plants green to brownish. Leafy stems simple, 18–60 mm long, 5.5–10.0 mm wide; axillary hyaline nodules lacking; central strand well differentiated. Leaves in 14–26 pairs, densely arranged throughout except the lowermost ones, which are widely separated and much smaller; middle and upper leaves lanceolate to narrowly lanceolate, 4.7–5.5 mm × 1.0–1.2 mm, acute at apex; base of dorsal laminae wedge-shaped, decurrent; vaginant laminae ca. 1/2 the leaf length, equal or slightly unequal; costa stout, percurrent; margins of the upper half of leaves irregularly dentate, the lower half almost entire, bordered throughout by a darker-colored band of 2–5 rows of incrassate, smooth cells, and 2–3 cells thick in cross section; cells of apical and dorsal laminae quadrate to hexagonal, moderately thick-walled, some smooth, some highly mammillose, 7–14 µm long; cells of vaginant laminae similar to those of apical and dorsal laminae, but usually smooth. Dioicous. Female inflorescences in axils of middle and upper leaves. Perichaetial leaves narrowly lanceolate to subulate-lanceolate, 2.5–2.8 mm long. Archegonia 426–640 µm long. Setae lateral, ca. 6.5 mm long, smooth; capsules slightly inclined, asymmetrical; urns 1.3–1.4 mm long; exothecial cells rectangular to irregularly rectangular-hexagonal, longitudinal walls not markedly thicker than transverse walls; opercula rostrate, 0.4–1.3 mm long; peristome teeth, ca. 0.4 mm long, 100 µm wide at base. Spores 11–18 µm in diameter.
