Plants large, robust, forming cushions, yellow-green to dark green; terricolous or saxicolous. Stems 80-120 mm high, irregularly branched, with sparse, red-brown tomentum on lower stem; in section subround to angular, central strand small, inner cortical cells in 8-10 rows, thin-walled, becoming smaller and thickened toward outside, outer cortical cells in 2 rows, stereids, reddish, epidermal cells thin-walled, quickly absent, stem fluted. Leaves ± crowded, erect-spreading to widespreading and little altered dry, widespreading wet, plicate only in extreme base; oval-acuminate, 4.4-5.5 mm long, 1.2-1.5 mm wide below; base scarcely differentiated, oval to weakly obovate; margins recurved to narrowly revolute, serrate to sharply serrate above mid-leaf. Costa percurrent to short-excurrent; superficial cells rectangular, smooth, incrassate; in section elliptical, bulging dorsally, guide cells 2, large, incrassate, ventral stereid band 1 cell thick, exposed, dorsal stereid band 1-2 cells thick, exposed. Laminal cells long-rectangular, 5-10:1, strongly thickened and pitted on lateral walls, end wall thinner, prorate proximally; 8-12 marginal cells slightly larger than laminal cells (obvious only in cross-section); basal cells long-rectangular, 10:1, strongly incrassate; alar cells broader, quadrate to rectangular, thin-walled, usually 3 cells wide by 7 cells high. Only immature sporophyte seen; seta to 15 mm long, capsule to 3 mm long; operculum short-conic.
