Plants green above, brown below, up to 2.5 cm high. Leaves crowded, tubulose and incurved when dry, spreading up to 70¡ when moist, nearly flat to broadly concave, 2-2.5(-3) mm long, ligulate to lanceolate, rounded to sharply acute at the apex; margins plane to erect; costa often very thick, short-excurrent as a stout mucro; upper cells subquadrate to hexagonal or short-rectangular, 6-9 µm wide and 1(-2):1, thin- to evenly thick-walled, each with 2-4 bifid to multifid papillae; basal cells differentiated across the insertion, rectangular, 9-13 µm wide and 2-4:1, thin-walled, hyaline. Dioicous. Setae 3.5-10 mm long; capsules 0.8-1.5 mm long, cylindric to broadly ellipsoid; annulus of 1-2 rows of usually weakly vesiculose cells, persistent, fragmenting, or revoluble; operculum 0.5-0.8 mm long, conic; peristome teeth often rudimentary, 30-300 µm long, straight, ligulate to subulate, entire or 2-3-forked, yellow to red-brown, spiculose to minutely reticulate, with basal membrane short or lacking. Spores 15-20 µm, strongly papillose.
