Ecology: Wet lowlands to open or wooded montane; often in exposed, wet habitats, frequently found along streams, on soil and rocks. Elevation: 100-3950 m (Venezuela: 160-800 m, Colombia: 110-2700 m, Ecuador: 200-3950 m. Peru: 100-1820 m, Bolivia: 170-2740 m, Argentina: 540 m). Distribution: Widespread; throughout the Neotropics, mostly at low elevations.

      Bryum apiculatum is distinguished by the somewhat imbricate, erect oblong leaves that are strongly concave, acute apex, unborded margins, long rhomboidal upper cells, short rectangular to subquadrate basal cells, and occasionally the presence of bulbous gemmae in the leaf axil of mid to upper leaves. Some authors have placed this species in Pohlia (in part due to the absence of a border and rather narrow laminal cells). Bryum cruegeri Hampe, a synonym, was previously used in earlier literature.
