Plants in dense or open turfs or scattered individuals, green, red-green, or yellow-green. Stems 0.5–2(–3) cm, tufted, comose, innovations elongate and evenly foliate; often strongly radiculose. Leaves yellow-green to red-green, weakly to strongly contorted or shrunken when dry, ovate-lanceolate, weakly concave, (0.6–)1–2(–3) mm, enlarged toward stem apex; base not decurrent; margins revolute to mid leaf, limbidium strong, in 2 or 3 rows; apex acuminate; costa long-excurrent, awn smooth to denticulate; proximal laminal cells 3–4:1, same width or narrower than more distal cells; medial and distal cells rhomboidal, 12–18 µm wide, 3–4:1, walls thin. Specialized asexual reproduction absent. Sexual condition synoicous. Seta 1–3 cm. Capsule brown, short to long pyriform, symmetric, 2–4 mm, mouth straight, orange or yellow; operculum short-convex, apiculate; peristome somewhat reduced; exostome teeth yellow basally, hyaline distally, lamellae straight to curved mid tooth, pores absent along mid line; endostome sometimes adherent to exostome, basal membrane high, 1/2 exostome height, segments with ovate perforations, cilia rudimentary or sometimes 1 or 2, long, appendiculate to nodose. Spores (18–)20–24 µm, finely papillose, pale yellow or green.
Habitat: Capsules mature Jun-Aug. Dry soil, alpine or arctic tundra, circumpolar arctic-alpine; low to high elevations (0-4400 m)
