Plants small to medium-sized, forming loose tufts, yellow-green to glaucous green; corticolous or saxicolous. Primary stems creeping, naked; secondary stems erect, 15-35 mm long; branching dense above stipe, subdendroid, fasciculate to pinnate, rarely flagellate, distinctly curved when dry; in section oval, central strand small, inner cortical cells thin-walled, yellow, in stipe 8-10 rows wide, 5 or 6 rows in branches, outer cortical cells smaller, thick-walled, yel low-brown, in stipe 6-8 rows wide, 3 or 4 rows in branches; paraphyllia absent; pseudoparaphyllia absent. Leaves crowded, erect-spreading wet, appressed dry; leaves on stipe broadly ovate, 1.0-1.5 mm long; acute; rounded at base; margins plane, weakly serrulate; branch leaves ovate to elliptical, 1.2-2.2 mm long; acute; rounded to cordate at base; margins plane, serrate. Costa short and double, occasionally broad at insertion and with 2-4 short spikes; in section flat, consisting of 3 rows of undifferentiated cells. Upper laminal cells short-fusiform to rhomboidal, somewhat sigmoid, homogeneous, 12-25 µm long, 7-8 µm wide, walls thickened, with a few sharply prorate cells on upper dorsal surface; basal cells oblong to linear juxtacostally, forming distinct groups, irregularly quadrate to transversely rectangular, green, walls thickened; alar cells in distinct group, quadrate.
