Plants moderately sized to fairly large, occasionally small, loosely or densely caespitose or forming extensive mats, yellow- or olive green, rarely dark green in the uppermost part, brown to blackish brown proximally. Stems (1–)3–8(–12) cm, prostrate to ascending, mostly pinnately branched, occasionally almost unbranched. Leaves appressed and slightly twisted when dry, erect-spreading to somewhat recurved when moist, ovate-lanceolate to subtriangular, 2–3 × 0.9–1.2 mm; margins broadly recurved to revolute throughout; apices gradually long-acuminate, sharply keeled, plicate, piliferous or not infrequently muticous, awns erect or sometimes reflexed-flexuose, capillaceous, slightly decurrent, weakly denticulate, slightly papillose to epapillose distally, slightly to strongly papillose in the basal part with low or sometimes high and narrow papillae; costa percurrent, lying at the bottom of a shallow and wide-angled furrow and strongly flattened in the basal part, (65–)75–100 µm wide; basal laminal cells elongate, 40–50 × 4–6 µm, with moderately thickened, nodulose and porose longitudinal walls, papillose with relatively low and narrow papillae, except for 1–4 epapillose cells at the insertion; alar cells rounded, thin-walled and hyaline in 3–5 rows, forming rounded and convex auricles; supra-alar cells elongate, with thin, straight or weakly sinuose walls, forming a transparent marginal border consisting of 10–15 cells; medial and distal laminal cells rectangular, 10–20 × 6–10 µm, papillose with relatively low and narrow papillae. Inner perichaetial leaves membranous, hyaline to yellowish hyaline, piliferous. Seta dark to reddish brown, lustrous, 12–15 mm. Capsule brown, long-cylindric, 1.5–2 mm, sulcate when dry; peristome teeth 600–800 µm, reddish brown to red, split to the base into 2 filiform branches, finely densely papillose. Spores 9–12 µm.
