Plants medium-sized, loosely caespitose or gregarious, green, ± glossy; corticolous or occasionally terricolous. Stems 2-5 mm long, radiculose below; in section cortical cells in 4-6 rows. Leaves appressed and spirally twisted around stem dry, spreading wet; elliptical, 1.0-1.8 mm long, apex acute, fragile, mucronate; margins reflexed from base to near apex, entire to weakly serrate at apex. Costa short-excurrent, mucro smooth, 0.1-0.5 mm long; in section bulging dorsally, guide cells 2, ventral surface cells 2, thin-walled, dorsal stereid band 3 cells thick, reddish, with hydroids below guide cells, dorsal surface cells weakly differentiated but larger and thin-walled laterally. Upper laminal cells mostly 2-3: 1, oblong-hexagonal, (35-)50-62(-75) µm cells narrower and slightly thickened, forming very weak border, 1(-2) cells wide; basal cells short rectangular, 2-3: 1. Perichaetial leaves ± triangular, smaller than vegetative leaves. Seta 8-14 mm long, yellow-brown; capsule suberect to horizontal, pyriform to clavate, 2.5-3.0 mm long, yellowish to brownish, neck sunken, to 1 mm long; exothecial cells irregular with wavy walls, at mouth regular and quadrate; peristome teeth narrowly lanceolate, 50 µm high, endostome with high basal membrane, segments as high as teeth, cilia rudimentary; operculum short-conical, reddish; spores round, 33-37 µm, brownish, papillose.
