Mniodendron colensoi

Tufts on soil, logs and occasionally rocks, usually pale green, somewhat glossy. Stipes erect, to 5.5 cm long, entirely covered with tomentum, with small spreading pseudoparaphyllia. Fronds palmate to umbellate, to 3.5 cm wide, with simple to sparingly pinnate branches. Stipe leaves widely spreading to squarrose-recurved, narrowly triangular, 2.7–3.9 mm long, 0.9–1.5 mm wide, concave at base; base usually very broadly cordate; apex gradually acuminate; costae shortly excurrent, containing numerous colourless crystals in the epidermis of the base; margins sparsely serrate near apices, plane, unistratose; laminal cells linear, 50–135 μm long, 3–4 μm wide, shorter at margin where up to c. 45 μm long, usually weakly prorate; alar cells enlarged, forming a large square group. Branch leaves erecto-spreading, triangular-lanceolate, 2.2–3 mm long, 0.65–1 mm wide, plane; apices gradually long-acuminate; costae short-excurrent, containing numerous colourless crystals in the epidermis of the base; margins serrate toward apices, recurved near base, unistratose; laminal cells linear, 40–100 μm long, 3–5 μm wide, shorter at margin, weakly prorate; alar cells inflated, rectangular, forming a rectangular group. Setae (2.5–) 3.5–4.5 (–5.5) cm long, pale red to dark brown, smooth. Capsules horizontal to pendent, usually shortly cylindric, sometimes obconic, deeply sulcate, weakly curved, 3.5–5.5 mm long. Opercula sharply rostrate from conic base, 2.5–3.5 mm long.
