Plants large, deep yellow-green or reddish brown to blackish brown with age, not hoary distally. Stems with stoloniform-flagelliform branches present. Leaves ± loosely imbricate, ± longitudinally plicate, moderately to distinctly plicate-sulcate when dry, 1.5-2 mm; margins recurved proximally, recurved or plane in apex, erose-denticulate at apex; apex erect to somewhat secund and spreading when dry, erect- to wide-spreading when moist, acute to abruptly short-acuminate, sometimes apiculate in larger leaves, concolorous, strongly channeled, multipapillose; alar cells ± isodiametric, smooth to mostly 3-papillose, walls thick, or thinner near insertion, region concolorous or more strongly pigmented in 1 or 2 rows, sometimes gradually forming excavate auricle; mid basal laminal cells quadrate in 1 row, becoming long-rectangular to linear, papillae 4-8, in 1 row, walls ± thin to thick, not to moderately porose, region more deeply yellow to yellow-orange at insertion in 1 or 2 rows, rarely to 1/5 leaf length; medial cells 3-4(-6)-papillose over lumen, papillae simple, low and irregularly rounded, walls thin to thick, even or weakly to strongly porose-sinuate; distal cells chlorophyllose, similar to and concolorous with medial cells, less papillose; apical cells occasionally hyaline, or chlorophyllose with pellucid margins. Sexual condition autoicous or paroicous; perichaetial leaves similar to vegetative leaves, longer, 2-2.5(-3) mm, margins entire. Vaginula with paraphyses many, smooth, not extending onto developing calyptra. Seta dark reddish yellow, (5-)7-14(-25) mm, stout, extending beyond perichaetial leaves. Capsule exserted, brown, red at mouth, cylindric-fusiform when dry, ellipsoid or sometimes ovate (broadest at base) when moist, (1.9-)2-2.2 mm, irregularly striate-wrinkled to irregularly furrowed when dry, smooth when moist, mouth narrow; stomata phaneroporic; operculum conic, stoutly, bluntly, and obliquely medium- to long-rostrate. Calyptra cucullate, 2-4 mm, covering to below mid capsule, naked. Spores 18-23 µm, finely and evenly papillose.
