7. Encalypta tianschanica J.-C. Zhao, R.-L. Hu & S. He   天山大帽藓   tian-shan da-mao xian
Novon 7: 320. 1997. Type. China: Xinjiang, Tian-shan Mountain Range, Guong-nes forest station, near Guong-nes river, 43o15'N, 84o45' E, J.-C. Zhao 953288-b (holotype HBNU; isotypes HSNU, MO).  
Plants small, to 6–8 mm tall, green to yellowish green above, bright brown below, in dense tufts. Stems simple or sparsely branched; central strand indistinct. Leaves slightly tortuose when dry, erect-spreading when moist, 2.2–3.5 mm long, obovate or spatulate, abruptly narrowed to a hyaline hair-point at the apex, the hair-point ca. 0.5 mm long, nearly smooth; upper leaf margins plane or nearly so; costa single, strong, ending well below the leaf apex; upper leaf cells small, irregular quadrate to rounded-quadrate, 18–25 µm wide, densely papillose, basal cells oblong 52–68 µm ×  20–24 µm, with thickened transverse walls, brownish yellow; 3–4 rows of basal marginal cells linear, 45–58 µm × 11–14 µm, thin-walled, pale in color. Autoicous. Perichaetial leaves the same as or slightly smaller than the upper stem leaves. Setae very short, 1.5–1.7 mm long, erect or slightly inclined, brownish yellow; capsules ovoid, smooth, suddenly contracted from a broad base to a very small mouth; peristome absent; annuli undifferentiated; opercula low conic-rostrate, with a long, slightly oblique beak. Calyptrae covering the whole capsules, smooth, often ragged at base, with an obtuse rostrum, ca. 1/3 the calyptra length. Spores 38–45 µm in diameter, heteropolar, with large, verrucate protuberances (warty papillae) on the distal surface, radially plicate on the proximal surface.
