Plants green to dark green, usually with a reddish cast. Stems to 2 cm, central strand present. Stem leaves often twisted, appressed to weakly spreading or spreading-flexuose when dry, spreading to spreading-recurved and not keeled when moist, monomorphic, lanceolate, grooved adaxially along the costa, especially near leaf apex, 0.8-2.5(-4) mm, base scarcely differentiated to oblong in shape, margins recurved below mid leaf or to above mid leaf, entire, apex acute, not fragile, commonly ending in a conical cell; costa percurrent or more commonly short-excurrent, not strongly spurred, not much widened or tapering, lacking an adaxial pad of cells, adaxial costal cells quadrate to short-rectangular, ca. 4 cells wide at mid leaf, guide cells in 1(-2) layers; basal laminal cells differentiated medially or across the leaf, walls thin to weakly thickened, rectangular or seldom quadrate, not perforated; distal laminal cells 7-10 µm wide, 1:1, nearly smooth or papillae simple or 2-fid, 2-3 per lumen, lumens irregular or oval to rounded-quadrate, walls thin or evenly thickened, convex on both sides of lamina, 1-stratose or occasionally 2-stratose in patches. Specialized asexual reproduction very rare, by multicellular gemmae in clusters in leaf axils. Seta 0.8-1 cm. Capsule 1.5-2.5 mm; peristome teeth 32, linear, twisted 1/2 to once, to 1300 µm, occasionally rudimentary or absent. Spores 9-12 µm. Distal laminal KOH reaction light to dark red-brown, occasionally deep red-orange.
