Plants medium-sized, loosely caespitose, brown-green to black-green or red-brown; saxicolous. Stems 10-20 mm long, irregularly branched; in section round, central strand absent, inner cortical cells in 3 rows, slightly thickened, outer cortical cells in 3 rows, smaller, incrassate. Leaves falcate-secund to almost circinate wet or dry; oval to oblong, long-subulate, 2.0-2.5(-3.0) mm long; margins plane, entire. Costa wide, filling subula; in proximal section flattened, cells in 2 rows, undifferentiated, strongly thickened; lamina unistratose; in distal section reniform, internal cells in 2-4, rows, small strongly thickened, dorsal and ventral surface cells thin-walled; lamina bistratose. Upper laminal cells rounded-quadrate, incrassate, bulging dorsally, smooth ventrally; basal juxtacostal cells rectangular. Perichaetia terminal; leaves sheathing, convolute, oval, short-acuminate to acute, 3.0-3.5 mm long. Pseudopodia light green, 2 mm long; capsules immersed to emergent, elliptical-apiculate, 1.0-1.2 mm long, red brown, dehiscence slits extending from base to apex; spores round, 25-35 µm, yellow, reticulate-papillose.
