Stems 4 cm, branches usually simple, short, blunt, densely foliate; epidermal cells small, walls thick, in 2 or 3 rows, surrounding larger, thinner walled cells, central strand small; rhizoids along underside; axillary hair basal cell 1, distal cell 1, relatively short. Stem leaves 0.8-1.2 mm; apex gradually and narrowly acuminate; costa unequal, one fork often ending 1/3-1/2 leaf length; alar cells in 6-12 rows in extreme basal angles; laminal cells linear to oblong-linear, walls firm; basal cells shorter, broader. Branch leaves usually wide-spreading, sometimes more imbricate, lanceolate to ovate-lanceolate, concave, 0.6-0.9 mm; costa unequal, one fork often ending 1/4-1/3 leaf alar cells in 4-10 rows in extreme basal angles. Perichaetial leaves 0.7-1.4 mm, margins plane, sparsely serrulate, costa often well developed, sometimes ecostate, alar cells not differentiated, laminal cells smooth or low-prorulose at distal ends abaxially. Seta twisted. Capsule0.7-1.1 mm, neck usually differentiated; exothecial cells quadrate to short-rectangular, vertical walls firm, cross walls thin and wavy; annulus 1-3-seriate, falling early, cells elongate, walls thick; exostome teeth shouldered, bordered, internal surface trabeculate; endostome basal membrane smooth or obscurely roughened, segments finely papillose, perforate, cilia finely papillose. Spores 11-19 µm.
