Stems in rather dense mats, 2–5 cm long, without tomentum, in section showing enlarged, usually collapsed, epidermal cells. Leaves only slightly twisted when dry, spreading-recurved from rather sheathing bases when wet, 3–4 mm long, 1.0–1.3 mm wide, lanceolate, carinate distally with narrowly acute apex; lower margins recurved, dentate in upper 1/3–1/2; costa percurrent to subpercurrent, semicircular in section with 4 guide cells, 2–3 rows of stereid cells abaxially; upper leaf cells subquadrate, 11–15 μm in diameter, with crowded, multifid papillae scattered over surface; apical cells mostly rhomboidal, scarcely papillose; inner basal cells 9–11 μm wide, 45–65 μm long, scarcely papillose; alar cells often yellowish brown with short, thick-walled cells. Setae 10–11 mm long, brown. Peristome 0.3–0.4 mm long. Spores 17–20 μm in diameter.
MAS AFUERA: Las Torres, ca. 1350 m, Sk. M159 (type, FH).
The species is also known from Mexico, Central America, Andes south to Argentina, southern Brazil, and the mountains of Africa. Juan Fernandez is the southernmost known locality for the species.
