Plants medium-sized to fairly large, rather slender but rigid, in loose or dense tufts or extensive mats, often hoary, dull green to olivaceous distally, brown to blackish proximally. Stems 2-6(-12) cm, prostrate to ascending, sparingly to copiously branched, often with numerous short branchlets. Leaves loosely imbricate, twisted or secund when dry, erect-spreading to patent when moist, lanceolate, channeled along the costa, (2-)2.5-3.5(-4.7) (with awns) × 0.6-0.9 mm; margins 1-stratose throughout with some 2-stratose spots distally, recurved on both sides towards the apex, sometimes strongly so on one side and usually less recurved on the other side; with a usually long, 0.5-1.5(-3) mm, prominent, erect, hyaline awn, flattened, often decurrent, distinctly denticulate at the margins, often somewhat flexuose and wrinkled and spinulose on the back side; costa percurrent or subpercurrent, channeled adaxially throughout, rather weakly convex on the abaxial side, (60-)80-110(-150) µm wide near the base, (40-)50-65(-75) µm wide distally, 3-4-stratose with (4-)5-9(-11) larger adaxial cells at the base, 2(-3)-stratose with (3-)4-8 adaxial cells in mid leaf and 2-stratose distally with 2-4(-5) adaxial cells; laminal cells 1-stratose, smooth or weakly bulging; basal laminal cells elongate, 15-35 × 8-10 µm, with thick, sinuous-nodulose walls; alar cells not or slightly differentiated, yellowish, sometimes forming a small group; supra-alar cells not differentiated; distal and medial laminal cells irregularly quadrate to rectangular, 10-25 × 8-10 µm, often becoming oblate at the margins in the distal part. Inner perichaetial leaves (1-4) hyaline, bluntly pointed, epilose. Seta brown, 4-9 mm. Capsule brown, somewhat glistening shortly cylindric, 15-30 × 0.5-0.8 mm; operculum with a long beak, to 1 mm; peristome teeth 250-380 µm, yellowish brown, papillose, irregularly cleft into 2 or seldom 3 prongs distally, or undivided, only with median perforations, arising from a rather short, 35-50 µm high, basal membrance. Spores 14-18 µm.
