Species Description - Plants growing in bright or yellowish green cushions, usually on wood. Stems creeping and rooting, irregularly pinnate, with ascending, more or less circinate, simple branches; leaves crowded, recurved or secund when dry, spreading when moist, with recurved tips and revolute margins, seldom reaching 1 mm. in length by 0.4 mm. wide, concave, with flat or revolute, entire margins; apex acute or short-acuminate; veins short and double, obscure or none; basal angles with 3-4 rows of square cells and a few larger inflated alar cells; upper cells rhomboid, about 35 times longer than wide; periehaetial leaves longer, up to 1.32 mm., erect and clasping, more acuminate, entire or finely subserrulate, ecostate with larger basal cells. Autoieous. Pedicel short, only 5 mm.; capsule 1-1.5 mm., erect or slightly inclined; neck distinct; lid with a long beak equalling the urn; peristome short and teeth yellow, with deep basal lamellae on the inside, dark basal segments, paler and papillose points; median line not deeply grooved; endostome with narrow pale papillose keeled segments, which are not perforate, and the cilia often absent; spores smooth, ripe in winter.
