Stems erect to inclined, 2-15 mm high, branching; in section angular, central strand present, inner cortical cells large, outer cortical cells in 1-3 rows, stereids or substereids. Leaves incurved, contorted dry, erect-spreading wet, somewhat distant; ligulate to oblong-lanceolate, 1.0-1.5 mm long; apex acute, mucronate; base appressed to stem; margins frequently recurved just above base, plane above, entire or irregularly dentate by smooth, yellowish marginal cells. Costa short-excurrent, ventral superficial cells quadrate to short-rectangular, papillose, dorsal superficial cells elongate, incrassate, sparsely papillose; in section reniform, guide cells 4, ventral stereid or substereid band 1 cell thick, ventral surface cells incrassate, papillose, dorsal stereid band 2-4 cells thick, dorsal surface cells undifferentiated. Upper laminal cells quadrate to rounded-quadrate, with 4-6 low, blunt papillae over lumen; basal cells larger, well defined, rectangular, smooth, reddish yellow. Dioicous. Male plants somewhat smaller, perigonia terminal; leaves with broadly sheathing bases. Perichaetia terminal; leaves oblong-lanceolate, to 2 mm long. Seta 0.7-1.2 mm long, reddish; capsule cylindrical, 1.0-1.2 mm long, reddish brown; peristome fragile, teeth erect, linear, frequently perforated below, spiculate, reddish yellow; operculum conical, 0.6 mm long; spores round, 17-20 µm, granulate to smooth.
