Plants green above, tan below, up to 5 mm high. Leaves tubulose and incurved when dry, spreading to 45¡ when moist, broadly and deeply concave, 1(-2)-3.5(-4) mm long, lanceolate, obtuse or occasionally acute and usually cucullate at the apex; margins erect or weakly incurved, often little or not papillose below in 1 row of cells; costa short-excurrent as a mucro or occasionally ending at or slightly below the apex; upper cells subquadrate to rounded-hexagonal, 6-10 µm wide, thin- to evenly thick-walled, with papillae bifid to multifid, 2-3 and scattered over the lumen (though crowded), or fused into a single low compound papilla; basal cells differentiated across the leaf, rectangular, 7-9 µm wide, 3-6:1, thick-walled. Dioicous. Setae 10-13 mm long; capsules 1.5-2.2 mm long, cylindric to long-ellipsoid; annulus of 2-3 rows of vesiculose cells; operculum 1-1.2 mm long, high-conic; peristome teeth straight, lanceolate to linear, 150-400 µm long, yellow to brown, papillose to spiculose, with basal membrane none or very low. Spores 10-14 µm, weakly papillose.
