Plants usually green to blackish green. Stems to 0.6 cm, central strand present. Stem leaves appressed, imbricated, incurved when dry, widely spreading and not keeled when moist, monomorphic, ovate to elliptical, broadly concave adaxially across leaf, usually 0.4-1(-2) mm, base scarcely differentiated in shape, margins usually recurved to revolute to near apex but sometimes plane, entire, apex obtuse to rounded, often strongly cucullate, not fragile; costa percurrent or ending a 2-6 cells below the apex, slightly broader at mid leaf, usually strongly spurred, little tapering, with a low adaxial pad of cells, adaxial costal cells quadrate, (4-)6-8 cells wide at mid leaf, guide cells in 1 layer; basal laminal cells differentiated somewhat medially or across leaf, walls weakly thickened or thin, rectangular, not perforated; distal laminal cells 7-10 wide, 1:1, papillae absent or low, simple or 1 multiplex, rather flat papilla per lumen, lumens oval to rounded-quadrate, walls convex on both sides of lamina, 1-stratose or occasionally 2-stratose in patches. Specialized asexual reproduction rare, by unicellular gemmae in masses in leaf axils. Seta 0.4-0.9 cm. Capsule 0.7-1.5 mm; peristome teeth absent to rudimentary, irregularly ligulate, to 65 µm. Spores 9-11 µm. Distal laminal KOH reaction light brown to medium orange-brown.
