Plants small, creeping over substrate or forming thick masses, yellow-green to light green; saxicolous or corticolous. Stems creeping, 10-40 mm long, branching irregular; in section round, central strand small, inner cortical cells in 4 rows, thin-walled, outer cortical cells in 3 or 4 rows, smaller, thick-walled, yellow-brown. Leaves distant, widespreading wet, reflexed and squarrose dry; stem leaves broadly ovate to ovate-lanceolate, 0.9-1.5 mm long; acuminate; rounded at base; margins plane, serrulate; branch leaves lanceolate to linear-lanceolate, 0.7-1.2 mm long; acuminate; rounded at base; margins plane, serrulate. Costa single, weak, extending to midleaf or beyond but always ending below apex, occasionally absent; in section consisting of an undifferentiated group of 4-6 cells. Upper laminal cells oblong-fusiform, 25-38 µm long, walls weakly thickened, papillose; papillae small, subseriate; basal cells not differentiated, somewhat broader; alar cells and cells along insertion smooth.
