Plants yellowish. Stems terete-foliate, irregularly pinnate, branches 5 mm, creeping or sometimes ascending and curved, subjulaceous; pseudoparaphyllia triangular to semicircular. Stem and branch leaves differentiated. Stem leaves straight or somewhat falcate, ovate-lanceolate, suddenly narrowed to apex, concave, not plicate, 0.8–1 × 0.2–0.4 mm; margins plane; acumen short; costa double, short; alar cells 6–12 along margins, in 6–9 rows; medial laminal cells 30–65 × 5–6 µm. Branch leaves oblong-lanceolate, larger, 1.1–1.2 × 0.3–0.4 mm. Seta 2–2.4 cm. Capsule erect to suberect, oblong-cylindric, 1.8–2 × 0.6–0.7 mm; exothecial cell shape variable; operculum rostrate, obliquely long-pointed; peristome reduced; exostome teeth lanceolate, 0.2 mm, base 50 µm wide, finely papillose distally; endostome adherent to exostome teeth, basal membrane well developed, segments 2-fid, split, internal surface roughly and finely papillose, segment and cilia connate. Spores 16–32 µm.
Phenology: Capsules mature late summer–early fall.
Habitat: Trunks of broad-leaved trees
Elevation: moderate to high elevations

Discussion
Pylaisia intricata is a rare species endemic to the flora area. The leaves are homomallous and erect-spreading when dry, wide-spreading when moist, and cordate at the base; the distalmost annulus cells are vesiculose and deciduous. The species is characterized by rather small branch leaves, long-pointed opercula, finely papillose external surface of the distal portion of exostome teeth, and adherent endostome; it can be distinguished from P. polyantha by its adherent endostome and larger spores.
