Plants small, yellowish to golden green or brownish, glossy. Stems 1–3 (–6) cm, not complanate-foliate, irregularly branched. Leaves appressed to erect-spreading, sometimes weakly secund, ovate; margins toothed at apex; apex broadly acute; ecostate or costa 2-fid; alar cells rounded, somewhat inflated, pigmented or not, walls thin, region in 1 row, middle lamella not apparent, supra-alar cells differentiated; laminal cells linear-flexuose to hexagonal, smooth. Sexual condition dioicous. Seta 1–1.5 cm. Capsule inclined, sometimes nodding when dry and operculate, ovoid to short-cylindric; exothecial cells with longitudinal walls slightly thicker than radial walls; operculum short-rostrate.

Distribution

North America, Mexico, Central America, Europe, Asia

Discussion

Species 4 or 5 (1 in the flora).

Hageniella was noted by B. C. Tan and Jia Y. (1999) to be identical to Schofieldiella as proposed by Buck. These authors also argued for its position in Sematophyllaceae, rather than Hylocomiaceae, where Buck placed it.
