Notes     (Last Modified On 5/6/2009)
general taxon notes:
Giraldiella levieri is characterized by having relatively large-sized leaves, inflated, subquadrate leaf alar cells, and especially long endostomal segments that are much longer than the exostome teeth. Reimers (1931) published Giraldiella levieri fo. laxifolia Thér. & Reim. and reported it from Guizhou, Hunan, Shaanxi, Sichuan and Yunnan provinces. However, no specimens under this name were availabel for examination. Its taxonomic status cannot be determined until the type is studied.

Leaves multi-seriate, appressed when dry, somewhat secund toward apex, erectopatent when moist, oblong-elliptic, 2.2–2.5 mm × 0.5–0.8 mm, strongly concave, gradually acuminate and shortly piliferous at apex; leaf margins entire, slightly incurved at base; costae double, very short; leaf cells linear-rhomboidal, 85–105 µm × 6–11 µm; alar cells quadrate, hyaline. Autoicous. Inner perichaetial leaves erect, somewhat sheathing at base, slenderly piliferous toward apex, margins entire. Setae slender, erect, reddish, flexuous above when dry; capsules erect or suberect, oblong-ellipsoidal, symmetric, gradually narrowed near base, with indistinct longitudinal ridges when dry; opercula conic, obliquely rostrate; annuli not developed; peristome double; exostome teeth narrowly lanceolate, 31–39 µm, yellowish brown, not cross-striolate on the dorsal surface, densely papillose above, with low and dense trabeculae on the inner surface; endostome segments slenderly lanceolate, pale yellowish, distinctly longer than the teeth, 41–45 µm long, densely papillose, perforate; basal membrane high; cilia single. Calyptrae not seen. Spores small, yellowish, 21–25 µm in diameter, densely minute-papillose.
