Plants growing in dense mats, yellowish or blackish green above, brown or blackish brown below. Stems branching occasionally, to 2 cm in length, occasionally papillose, transverse section rounded-triangular to five-sided, central strand absent, sclerodermis present, of 1-3 layers of stereid cells, hyalodermis absent; axillary hairs 6-9 cells in length with cells weakly bulging, basal 1-2 cells very weakly thick-walled; sparsely radiculose below. Leaves in 3 distinct rows, the rows straight or weakly spiralling counter-clockwise, appressed-incurved to weakly spreading when dry, widely spreading to spreading-recurved when moist, ovate-triangular, 1.0-1.4(-1.7) mm in length, upper lamina keeled, narrowly channelled along costa, margins recurvedin lower 2/3 to 3/4 of leaf, entire; apex narrowly acute to short-acuminate; base ovate, basal leaf margins broadly long-decurrent; costa percurrent, superficial cells elongate and smooth or weakly papillose ventrally, rhombic-quad-rate near apex and smooth or papillose dorsally, 2(-4)rows of cells across costa ventrally at mid-leaf, costal transverse section ovate to semicircular, ventral epidermis absent, dorsal stereid band usually absent, guide cells 2-4 in1 layer, hydroid strand absent, dorsal epidermis differ-entiated as thick-walled cells with semicircular lumens; upper laminal cells rounded-rhombic to quadrate, 8.4-10.5 mm in width, 1:1, occasionally elongate transversely, walls thickened, weakly trigonous, superficially weakly convex on both sides; papillae small, low, bifid, 4-6 perlumen; basal cells differentiated weakly as a single row of slightly elongate cells at leaf insertion. Dioicous. Perichaetia terminal but often appearing lateral because of sub-perichaetial inovation, inner leaves ovate to elliptic, to 2.2 mm in length, strongly sheathing seta, apex short-acuminate and reflexed, lower cells rhombic, upper cells narrowly rectan-gular to rhombic, thick-walled throughout. Perigonia lateral, borne in leaf axils; bracts ovate to nearly circular. Seta 0.9-1.5 cm in length, 1 per perichaetium, yellow, twisted clock-wise above. Capsule 1.0-1.8 mm in length, yellowish brown, elliptical, annulus of ca 3 rows of smaller, vesiculose cells; peristome teeth 16, cleft to base, blunt, subulate, transparent or pale yellowish, mostly smooth or some teeth weakly spirally striate in part, 110-130 mm in length, with ca 4-6articulations, straight, basal membrane absent; operculum bluntly conic, ca 0.5 mm in length, cells straight. Calyptra smooth, ca 2.2 mm in length. Spores ellipsoidal to spherical, 12-20 mm in diameter, yellowish brown, finely papillose.
