Characteristics

Plants large, coarse and rigid, loosely caespitose of forming wide patches, olivaceous to greenish, occasionally somewhat grayish in the upper part, brown proximally. Stems 3-4(-11) cm, ascending to erect, almost unbranched to dichotomously branched, rarely more profusely irregularly branched. Leaves erect to slightly recurved when dry, erect-spreading when moist, stiff, broadly lanceolate, 3-4 × 0.7-1 mm; margins broadly revolute to recurved throughout on both sides, 2(-3)-stratose distally in 2(-3) rows of cells; piliferous, awn short, 0.1-1 mm, stiff, straight or weakly flexuose, faintly or distinctly denticulate and spinulose; costa robust, percurrent, usually broadly canaliculate in mid leaf, strongly convex on the abaxial side, 80-120 µm wide basally and 50-65 µm wide distally, 3-4(-5)-stratose in the basal and median parts with 4-9 not enlarged cells on the adaxial side, elliptical to rectangular in outline in cross-section; laminal cells smooth, 1-stratose; basal lamianl cells long-rectangular to linear, 20-70 × 7-9 µm, porose and nodulose; alar cells not or slightly differentiated; basal marginal border not differentiated; medial and distal laminal cells short-rectangular, 5-25 × 5-9 µm. Inner perichaetial leaves strongly modified, hyaline, membranous, ovate with a short apex. Seta brown, 3-5 mm. Capsule brown, narrowly cylindric, 1.5-2.5 × 0.45-0.5 mm; peristome teeth 400-500 µm, densely papillose, irregularly 2-fid, arising from a low, to 25 µm, basal membrane. Spores 12-17 µm.
