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.
