1. Sphaerotheciella koponenii P.-C. Rao   科氏球蒴藓   ke shi qiu shuo xian
Bryologist 103: 739, f. 1–16. 2000 [2001]. Type: China. Hunan, Sang-zhi Co., Koponen et al. 55709.
Plants stout, yellowish green when young, dark brown when old, in dense mats. Primary stems creeping; secondary stems 4–6 cm long, more or less densely pinnately branched; paraphyllia absent; pseudoparaphyllia present, filamentous; central strand absent. Stem leaves imbricate when dry, spreading when moist, concave, ovate at the base, more or less abruptly narrowed to a short acumen, 1.2–1.8 mm × 0.6–1.0 mm; margins slightly recurved from the base to above mid-leaf, nearly entire except somewhat serrulate at the apex; costae stout, ending in leaf apex; median and upper leaf cells elliptical, rounded-rhombic or rounded-quadrate, 8–16 µm × 7–10 µm, slightly smaller at margin, thick-walled; basal juxtacostal linear-rhomboidal, 35–80 µm × 4–7 µm, somewhat prorate; alar region consisting of a group of subquadrate cells; branch leaves smaller, similar to stem leaves in shape. Autoicous. Inner perichaetial leaves oblong-lingulate, abruptly contracted to an aristate apex; costae excurrent. Setae very short; capsules immersed, subglobose; opercula conic; columella persistent; peristome double; exostome teeth lanceolate, cross-striolate below, densely papillose above; endostome segments fragile, shorter than the teeth, smooth. Spores endosporic, ca. 40 µm in diameter, smooth. (The description is mainly adopted from P.-C. Rao 2000 [2001] with modification).
