Plants medium-sized to large, scattered and gregarious, glaucous green; saxicolous or corticolous. Primary stems long-creeping; secondary stem erect, 10-35 mm long, branching regular, pinnate above stipe; in section round, central strand absent but with central cavity, inner cortical cells thin-walled, hyaline, in 8-12 rows, outer cortical cells larger, thick-walled, brown, in 3-6 rows, epidermis absent. Leaves in ranks, dimorphic, widespreading wet, contorted dry, asymmetrical; stem leaves ovate or panduriform, 1.8-2.2 mm long; obtuse and cuspidate; rounded at base; margins plane, serrulate throughout but stronger above, unistratose, bordered by elongated hyaline cells; amphigastria broadly ovate, abruptly narrowed, 1.2-1.6 mm long; branch leaves lanceolate to elliptical, 1.2-1.5 mm long; acute and cuspidate; rounded at base; margins plane, serrulate throughout, somewhat stronger above, unistratose, bordered by elongated hyaline cells; amphigastria lanceolate to ovate-acuminate, 0.6-1.0 mm long. Costa single, shortly excurrent, displaced proximally in lateral leaves; ventral and dorsal surfaces smooth, cells elongate; in section elliptical, cells in 3 rows, smaller, incrassate. Upper laminal cells rounded quadrate to rectangular or transversely rectangular, homogeneous, 10-15 µm long, in amphigastria 5-7 µm long, walls incrassate to somewhat collenchymatous, smooth; basal cells not differentiated, walls thickened and pitted, smooth; alar cells not differentiated. Gemmae on stem and branches, in small groups, cylindrical, 200-400 µm, brown, papillose. Sporophyte not seen.
