Stems 5 – 8 mm, simple, cross-section of stem rounded to oval, diameter 0.11 – 0.15 mm, central strand present. Leaves homomallous, falcate-secund when dry, erect-spreading when moist. Leaves lanceolate at base, gradually tapering into a channelled acumen; costa excurrent as an awn, mamillose dorsally, in transverse section with differentiated guide cells, with dorsal and ventral epidermis and few substereids on dorsal side of guide cells or poorly differentiated; margins plane or slightly incurved distally, entire or crenulate in distal part of acumen; lamina unistratose, occasionally partially 2 - stratose in distal portion, margins 1 - stratose; distal and median laminal cells short rectangular to subquadrate, with moderately thickened walls, (6 –) 8 – 15 (– 19) × 4 – 8 µm; basal juxtacostal cells elongate-rectangular, moderately thick-walled, non-porose, 30 – 50 × 5 – 9 µm; alar cells gradually enlarged, not sharply differentiated, unistratose, scarcely inflated, composed of short-rectangular to quadrate inflated cells, non-porose, 24 – 45 × 14 – 20 µm. Autoecious. Perigonia terminal closely located below the perichaetia. Perigonial leaves small, ovate-lanceolate to triangular, 0.65 – 0.75 × 0.45 – 0.55 mm, costa present or absent; Perichaetial leaves with sheathing base, abruptly into a channelled acumen. ca. 3.2 mm long.
