Plants small, yellow-green to green above, yellow-brown to brown below; saxicolous to terricolous. Stems up to 28 mm tall, branching by subperichaetial innovations, scarcely tomentose below; rhizoids red or reddish brown, smooth to papillose; in section subround to subtriangular, inner cortex 4-8 cells across, thin-walled, outer cortical cells smaller, in 1 or 2 rows, rarely absent on one side, incrassate, minutely papillose. Leaves crowded, ± equal in size, erect and crisped when dry, erect-spreading and flexuose when wet; linear-lanceolate to linear, 2.0-4.8 mm long; apex acute to acuminate, with a single apical tooth; margins plane, frequently recurved on one side below, irregularly serrate, frequently denticulate at shoulders, rarely decurrent. Costa ending below apex; ventral and dorsal superficial cells narrowly rectangular; in section crescent-shaped to subround, bulging dorsally, ventrally flat, laminal insertion ventral, guide cells in one layer medially, ventral substereid or stereids in one layer, papillose, dorsal stereids in 1 or 2 rows, surface rough. Upper laminal cells rounded-quadrate or oval, incrassate, bulging ventrally, papillose, striolate, 6-14 µm, papillae low, blunt, scattered over dorsal and ventral surface; basal cells rectangular, thin-walled, smooth to striolate. Autoicous. Perigonia terminal on short, subperichaetial branches; inner leaves ovate to ovate-apiculate to ovate-acuminate, margins irregularly crenulate. Perichaetia terminal, frequently overgrown by subperichaetial innovations; leaves scarcely differentiated, linear-lanceolate, 2.5-3.8 mm long, sheathing below, base oblong or oval. Seta 0.9-1.5 mm long, frequently curved, yellowish. Capsule erect to inclined, immersed, urceolate, brownish, urn 0.3-0.5 mm long, neck 0.2-0.3 mm long; exothecial cells irregularly rhomboidal to rectangular, ± thin-walled, in 2 or 3 transverse rows at mouth, smaller at mouth; stomata present on neck. Operculum conic-apiculate, oblique. Calyptra 0.5-0.6 mm long, cells smooth to papillose. Spores 12-22 µm.
