Dicranella divaricatula Bescherelle 1898

This species resembles Dicranella divaricata (Mitt.) Jaeg., but it differs from the latter by having leaves without sheathing bases. P.-C. Wu (1992) recently reported the latter species from Yunnan, but we could not confirm this report.

Plants slender, 1–3 cm high, yellowish brown, gregarious or in loose tufts. Stems erect, simple, rigid, somewhat radiculose at base. Leaves distant, erect or flexuose-spreading, linear-lanceolate, rather abruptly narrowed from a nearly triangular, nonsheathing base to a subulate acumen; margins plane, entire or only serrulate at the apex; costa percurrent to shortly excurrent, smooth at back; upper cells rounded rectangular; lower cells shorter, broader, and rectangular. Dioicous. Perichaetial leaves sheathing at base, abruptly narrowed from the shoulder to a long subulate acumen. Setae straight, up to 1.5 cm long, yellowish; capsules erect, elongate-ovoid, up to 1 mm long, smooth when dry, without struma; opercula long-rostrate, nearly as long as the urns; annuli in 1 row of cells; peristome teeth short, divided to the middle, reddish and vertically striolate below. Spores not seen.

Distribution: endemic to China.

Habitat: on wet or sandy soil near roadsides or streams.
