Plants small to medium-sized, rarely fairly large, forming loose or dense tufts or mats, green, yellowish or olive green to light yellowish or sometimes grayish in the upper part, brown to blackish proximally, not or hoary. Stems prostrate to erect-ascending, (1-)2-4(-7) cm, copiously branched, mostly with short lateral, tuft-like subpinnate branchlets giving the plants a nodose appearance. Leaves loosely imbricate and often secund on drying, erect-spreading to recurved when moist, (1.5-)2-3.4(-3.8) × (0.4-)0.5-0.7(-0.8) mm, keeled in the distal part, narrowly canaliculate basally, piliferous or seldom epilose; hair-point erect, hyaline, capillaceus, flexuose, 0.3-0.7(-1.1) mm, not or slightly decurrent down the leaf margins; margins broadly recurved to revolute on one or both sides for 1/2-3/4 the leaf length, rarely to the apex, 1-stratose throughout, sometimes with 2-stratose patches; costa percurrent, convex abaxially, (50-)60-80(-100) µm wide near the base, (35-)40-55 µm wide distally, 2-3-stratose basally with (2-)3-4(-5) markedly enlarged adaxial cells, 2-3-stratose in the middle with 2-3(-4) large adaxial cells and 2-stratose distally with (1-)2(-3) adaxial cells; laminal cells 1-stratose, smooth or often strongly pseudopapillose; distal and median cells strongly sinuose, rectangular, 20-30 × 9-10 µm, becoming shorter or oblate towards the margins; basal cells elongate to linear, 25-95 × 8-12 µm, with strongly incrassate and porose walls; alar cells not or weakly differentiated; basal marginal cells quadrate to short-rectangular, rarely long-rectangular, esinuose or very seldom sinuose, hyaline or very rarely chlorophyllose, forming pellucid, 1(-2)-seriate border of (5-)10-20(-25) cells, very occasionally not transparent. Innermost perichaetial leaves (4-6), markedly modified, ovate, acuminate, epilose or very seldom piliferous, hyaline to yellowish hyaline in the proximal half, chlorophyllose in the distal half with strongly incrassate cell walls. Seta dark red to reddish brown, (2.5-)4.5-8 mm. Capsule obloid-cylindric to elongate-ovoid, (1.2-)1.5-2 × 0.3-0.6 mm, brown, dull to weakly lustrous; peristome teeth yellow-reddish, 310-350 µm, papillose, irregularly divided nearly to the base into 2 prongs, sometimes only with elongate perforations, without or with a low basal membrane, 10-15 µm high. Operculum conical-rostrate, to 1 mm, with a straight or slanted beak. Spores (10-)12-14(-16) µm.
