DISTRIBUTION AND HABITAT. — Known from Europe (the Canary Islands) and Asia (China) (Fig. 3). In China, it grows on moist and shady soil, from 3744 m to 3828 m (Fig. 4). The elevation of the populations in China is much higher than that of the type locality, which is from 100 m to 1640 m.</p> <p>40°W 20°W 0° 20°E 40°E 60°E 80°E 100°E 120°E</p> <p>DESCRIPTION</p> <p>Plants in rosettes, irregular patches or gregarious; terrestrial. Thalli small to medium-sized, 0.8-2.1 mm wide, 5-8 mm long; (1-)2-3-times furcated, shortly to deeply divided. Dorsal surface glabrous, glistening greyish-green when wet, dull, scurfy when dry; median furrow distinct at apex, but immediately become shallow and disappears posteriorly. Dorsal epidermis 2-5-stratose, cells spherical or ovoid, hyaline, in loose cell pillars. Thallus sections of lobes 0.82-1.2 mm high and 1.5-2 times as wide; air chambers absent, but consist of a series of photosynthetic filaments, 8-10 cells high. Storage tissue cells irregularly rounded, thin-walled. Ventral scales prominent, hyaline white, never purplish or violet, wavy, quadrate to hexagonal, mostly going beyond thallus margin, thin-walled. Cilia absent. Rhizoids smooth and pegged. Monoicous. Antheridia scarce, conspicuous near median furrow. Spores tetrahedral, 83-100 µm in diameter, dark brown or blackish; distal surface largely lacunose, low radiating ridges run over distal face, gradually forming small areolae, 3-10 µm in diameter; proximal surface with straight or fragmented trilete mark, distinct, areolae incomplete with papillae or short tubercles at the corners; wing distinct, 7-9 µm wide.</p></div> 	https://treatment.plazi.org/id/41348935FFE4617A32C4F8FFFF4CF871	Public Domain	No known copyright restrictions apply.
