Characteristics

Plants medium-sized to large, in large, dense or loose tufts or mats, grayish olive or olivaceous in the distal part, brown or grayish proximally. Stems (1-)3-10(-13) cm, creeping, decumbent to ± erect, mostly pinnately branched with short, tuft-like branchlets, usually distinctly recurved at the apex. Leaves imbricate, not altered on drying, recurved when moist, ovate-lanceolate to subtriangular, indistinctly plicate, 2-3.2 × 0.8-1.2 mm; margins broadly recurved throughout; apices sharply carinate, most often piliferous, awns recurved to reflexed, subulate, strongly denticulate, mostly long-decurrent, slightly to distinctly papillose distally, strongly papillose basally with high and narrow papillae; costa percurrent, situated at the base of a moderately deep, wide-angled channel and strongly flattened basaly, 75-100 µm wide; basal laminal cells long-rectangular, 20-50 × 4-6 µm, moderately thick-walled, nodulose, papillose with large papillae, except for 1-4 rows of epapillose cells at the insertion; alar cells hyaline, thin-walled in 3-5 rows, forming a sharply delimited, convex group; supra-alar cells short, thick-and sinuose-walled, forming non-transparent border of 6-10 cells; medial and distal laminal cells subquadrate to rectangular, 6-20 × 5-8 µm, distinctly papillose. Inner perichaetial leaves hyaline, piliferous. Seta brown, glistening, 10-15 mm. Capsule brown, long-cylindric, 1.4-1.8 mm, sulcate when dry; peristome teeth 650-800 µm long, reddish brown to red, split to the base into 2 filiform prongs, densely papillose. Spores 9-11 µm.
