Stems 5-15 mm. Leaves clasping at base, infolded and twisted around the stem when dry, wide-spreading (in smaller forms) to squarrose-recurved when moist, lingulate-ovate, 1.5-3.5 × 0.75-1.25 mm, canaliculate to keeled; margins tightly revolute in the proximal 7/8 or more, entire; apices emarginate to acute; costa excurrent into a serrate (or occasionally only faintly serrulate), hyaline awn that is often red or sometimes broadly hyaline at base, weakly to strongly papillose on the abaxial surface and often serrate near the apex because of projecting cell ends, red-brown; basal cells abruptly differentiated, narrowly rectangular, 35-70(-90) × 11-18 µm, quadrate to narrowly rectangular at the margins; distal cells quadrate to polygonal, 8-12 µm, with 3-6 papillae per cell, bulging, somewhat obscure. Specialized asexual reproduction absent. Sexual condition dioicous. Seta red, 5-10 mm. Capsule red-brown, 2-3.5 mm, straight, with an abrupt neck; operculum 1.25-1.75 mm, brown; peristome ca. 1.25 mm, the upper divisions twisted ca. 2 turns, red, the basal membrane white, about 1/3 the total length. Spores 11-15 µm, papillose.
Plants large. Stems 5-15 mm long, central strand absent. Leaves wide-spreading to squarrose-recurved when wet, oblong-spathulate, 1.5-3.0 mm long; apex emarginate or truncate; margins revolute to upper leaf; costa long-excurrent as hyaline dentate awn; papillose to spinose on dorsal surface. Upper laminal cells hexagonal, papillose; basal cells abruptly differentiated, narrowly rectangular, hyaline. Capsule straight, peristome teeth twisted.
