Notes     (Last Modified On 12/13/2011)
general taxon notes:
Ulota gymnostomacan be easily separated from other Chinese species of Ulota by its gymnostomous capsule with a puckered mouth. It is gametophytically and geographically similar to U. crispa, but it differs from the latter by the broadly incurved leaf base differentiated with a narrow, hyaline band.

2. Ulota gymnostoma S.-L. Guo, Enroth & Virtanen   无齿卷叶藓   wu chi juan ye xian
Ann. Bot. Fenn. 41: 459. 2004. Type: China. Hunan, Changsha, Liu-yang Co., Virtanen 62091 (H).
Plants small, light green above, brown to dark green below, in tufts. Stems erect, 1.0–1.5 cm long, densely foliate, often branched. Leaves slightly twisted to strongly crisped when dry, erect-spreading to curved-spreading when moist, linear-lanceolate from an ovate, concave base, 1.2–4.5 mm long, constricted above shoulder, somewhat plicate at the leaf base; margins broadly incurved at the base, plane above; costae strong, nearly percurrent; all leaf cells smooth; upper and median cells irregularly rounded-quadrate or shortly elliptical, 6–17 µm × 9–17 µm, thick-walled; basal juxtacostal cells sublinear to narrowly rectangular, 27–58 µm × 4–7 µm, yellow, becoming shortly elliptical, thicker-walled above, gradually becoming short-rectangular to quadrate toward margin; alar cells differentiated in 3–6 rows of hyaline or sometimes yellowish brown cells, forming a distinct border. Autoicous. Perichaetial leaves hardly differentiated from vegetative leaves. Setae straight, 1.0–1.5 mm long; capsules exserted, erect, oblong-ovoid, 1.9–2.3 mm × 0.7–1.1 mm, constricted below the mouth, forming an 8-plicate and puckered mouth when dry, with a crinkled neck, gradually narrowed to the seta; opercula shortly rostrate; stomata superficial; peristome absent. Calyptrae mitrate, smooth, somewhat lobed at the base, with numerous yellow, slightly papillose hairs. Spores spherical, 27–40 µm in diameter, often endosporic, finely papillose.
