Plants small, green or yellow-green, often with reddish tinge. Stems 0.4–1.5(–2) cm; rhizoids yellow. Leaves imbricate to loosely set, ovate-lanceolate to narrowly ovate, weakly concave, 0.4–1.5(–2) mm; base not decurrent; margins revolute proximally, serrulate distally, limbidium absent; apex acute to acuminate; costa excurrent to long-excurrent, awn stout; alar cells similar to adjacent juxtacostal cells; proximal laminal cells gradually quadrate to short-rectangular, 1–2:1; medial and distal cells 50–60(–70) × 12–14(–16) µm, 3–4:1. Specialized asexual reproduction by rhizoidal tubers, on long rhizoids in soil, yellow or rarely orange, ± spheric, (100–)120–180(–200) µm, cells 25–40 µm, smooth. Sexual condition dioicous or rarely synoicous. Capsule inclined or nutant, 2–3(–4) mm.
Phenology: Capsules mature Apr–Jun (spring–summer).
Habitat: Damp to drying acidic soil
Elevation: low to moderate elevations (0-600 m)
