Stems to 2.5 cm. Leaves 2–4 (–5) mm, linear-lanceolate, tapering to a fine-point; distal leaf margins broadly recurved in the proximal half; distal lamina cells more or less scattered mammillose-papillose but smooth at leaf margins, distal and medial cells 10–14 µm. Perigonium sessile. Seta (0.6–) 0.9–1.3 cm, straight wet or dry. Capsule curved, zygomorphic, strumose; annulus of large, deciduous cells.


Phenology: Capsules mature summer.
Habitat: Shady, acid rock, soil over rock
Elevation: moderate to high elevations
