Plants small to medium-sized, up to 3 cm high, yellowish green above, brownish below, in dense tufts. Stems erect, simple or sparsely branched, crowdedly foliate, densely radiculose below. Leaves ca. 7 mm long, moderately crispate when dry, erect-spreading to strongly squarrose when moist, lanceolate from an erect, sheathing and strongly clasping base, rather abruptly narrowed from the shoulder, subulate to canaliculate toward the apex; margins undulate at the sheathing base, crenulate to serrulate near the apex, unistratose; costa broader at the base, reddish brownish, percurrent to shortly excurrent; upper cells rectangular to quadrate, from 20–30 µm × 6–9 µm to 9–14 µm × 9 µm, thick-walled, the cells near the margins becoming longer; lower cells in the sheathing base, rectangular, thin-walled, 50–75 µm × 8–12 µm, the cells near and above the shoulder becoming thick-walled and porose; alar cells not differentiated. Dioicous. Perichaetial leaves erect, with narrow limbs. Setae single, straight, 2–8 mm long, light brown; capsules slightly elongate-ovoid, erect, ca. 2.2 mm × 0.7 mm; peristome teeth reddish brown, dicranoid, spreading when dry. Spores brownish, warty.

Habitat: on rotten wood and bases of trees, rarely on rocks; Distribution: China, Nepal, India, Myanmar, Indonesia, and the Philippines.

Symblepharis guizhouensis was established by Tan et al. (1994) on the basis of S. breviseta Bartr. The species was published primarily based on its short setae [2–3(–6) mm long]. However, the seta length of S. guizhouensis is clearly within the range of setae found in S. reinwardtii.
