Plants usually blackish green. Stems to 1(-1.5) cm, central strand present. Stem leaves spreading-incurved and twisted to incurved-appressed when dry, spreading to spreading-recurved and not keeled when moist, monomorphic, short-lanceolate or sometimes short-ovate to long-elliptic, broadly concave adaxially across leaf, usually 1-2.5 mm, base scarcely differentiated in shape to ovate, margins usually recurved at mid leaf, entire, apex broadly acute or occasionally narrowly so, not fragile; costa percurrent or ending a few cells below the apex, broader at mid leaf, occasionally weakly spurred, with a low adaxial pad of cells, adaxial costal cells quadrate, 4-6 cells wide at mid leaf, guide cells in 1-2 layers; basal laminal cells differentiated medially or across leaf, quadrate to short-rectangular, walls very thin and not perforated; distal laminal cells 7-12 wide, 1:1 or occasionally transversely elongate below, papillae usually distinct, low or simple to 2-fid, occasionally absent, lumens oval to rounded-quadrate, walls thin to evenly thickened, convex on both sides of lamina, 2-stratose in one or more rows along margins. Specialized asexual reproduction by multicellular tubers on proximal rhizoids. Seta 0.7-1 cm. Capsule 1-1.9 mm; peristome teeth 32, linear, weakly twisted, to 600 µm, occasionally rudimentary. Spores 11-15 µm. Distal laminal KOH reaction variously negative or yellow-or orange-or red-brown.
