Plants to 10 cm, in loose, irregular mats or dense pure cushions, yellow, yellow-green, or brown to blackish when growing suboptimally. Stems yellow, yellowish green, or yellowish brown; cross section pentagonal, cortical cells in 4-6 irregular layers, outer medulla cells thicker walled than inner, central strand conspicuous, sometimes degraded; rhizoids between leaves throughout plants, conspicuous when dry or moist, or visible among leaves at base of plants. Leaves distant and not covering rhizoids, or imbricate and rhizoids mostly hidden, undulate, twisted or straight when dry, erect-spreading when moist, broadly to narrowly lanceolate, widest at base, often concave; base not rounded to insertion; margins revolute usually one time, sometimes more, in proximal 2/3, irregularly serrulate at apex; apex acute, acuminate, or narrowed, rounded, and somewhat cucullate; costa flexuose; laminal cells rounded quadrate, short-rectangular, or elliptic, papillae large; basal cells often 2-stratose at insertion, walls brown. Specialized asexual reproduction by bullet- or spearpoint-shaped propagula, flat at attachment, in terminal cluster. Perigonia as terminal discoid splash platforms; paraphyses of 8-12 cells. Perichaetia with paraphyses absent. Seta 3-5 cm. Capsule inclined to horizontal, 3-4 mm; operculum short-rostrate, rostrum blunt; endostome cilia nodose. Spores 10-15 µm, smooth.
