BEE0DFCF2586538EA19407DB46AC2158.taxon	diagnosis	Diagnosis. Particularly distinctive features of the new species including: double peristome; the exostome has raised and membranous chomata with united lamellae between two teeth proximally; the endostome is poorly developed and all the endostomial material tightly adherent to the exostome.	en	Wang, Xiao-Rui, Li *, Min, Spence, John R., Zhao, Jian-Cheng, Mamtimin, Sulayman (2021): Haplodontium altunense (Bryaceae, Bryopsida), a new moss species from Northwest China.

BEE0DFCF2586538EA19407DB46AC2158.taxon	description	Description. Plants small, soft and dull, brown-green. Stems short, 2.5 - 6 mm high, weakly julaceous, branched, circular or pentagonal circular in transverse section with small and thick-walled peripheral cells surrounding 2 - 3 layers gradually larger and thin-walled cortical cells, central strand weakly developed. Leaves imbricate when dry, erect when moist, enlarged towards stem apex, ovate to broadly ovate, concave, 0.5 - 1.1 x 0.3 - 0.7 mm; base not decurrent; margins plane or recurved medially, 1 - stratose, limbidium absent, smooth or finely serrulate distally; apex broadly acute; costae not reaching apex, guide cells weakly developed, 2 - 4 in one layer in costal transverse section, ventral and dorsal stereid bands present; alar cells not differentiated from juxtacostal cells; laminal cells lax; distal laminal cells rhomboidal, 30 - 44 x 11 - 21 μm, with slightly thickened walls; medial laminal cells long rhomboidal to rectangular, 37 - 69 x 12 - 20 μm, somewhat narrower in 2 or 3 rows toward the margins but not forming a distinct border; proximal laminal cells long rectangular, 37 - 56 x 20 - 28 μm. Dioicous (?). Perigonia not seen. Perichaetia at the end of short, inconspicuous stems, appearing laterally because of well-developed innovations; perichaetial leaves larger than vegetative leaves. Setae single, light brown, 15 - 19 mm long. Capsules nutant and symmetric, reddish brown, obovoid, 1.5 - 2 mm, neck short and indistinct, mouth small, stomata abundant in the neck, superficial; opercula long-conic with short rostrate; annulus present, consisting of two rows of cells, revoluble and cells with slit-like lumen; peristome double, exostome inserted below the mouth, teeth lanceolate, red-brown and pored, raised and membranous chomata with united lamellae between two teeth proximally, pale yellow to hyaline and largely papillose along horizontal and median vertical lines distally; endostome poorly developed, basal membrane smooth, segments and cilia rudimentary, all the endostomial material strongly adhere to the exostome. Spores spherical, 20 - 22 μm in diameter, minutely papillose.	en	Wang, Xiao-Rui, Li *, Min, Spence, John R., Zhao, Jian-Cheng, Mamtimin, Sulayman (2021): Haplodontium altunense (Bryaceae, Bryopsida), a new moss species from Northwest China.
