Ecology: Upper open montane to páramo and puna; on soil and rocks, occasionally epiphytic. Elevation: 2500-4900 m (Venezuela: 2500-3400 m, Colombia: 3100-3685 m, Ecuador: 3400-4000 m, Peru: 3650-4050 m, Bolivia: 3000-4900 m). Distribution: Central America, West Indies and tropical Andes.
Campylopus albidovirens is distinguished by the presence of microphyllous branches in the axils of upper leaves, leaves in cross-section with ventral hyalocysts, dorsal cells of hyalocsts alternating with chlorocysts that extend gradually into the lamina, basal cells elongate and thin-walled, and alar cells extending into the costa region. The type of this rather widespread tropical montane species was originally collected by Herzog along the upper slopes of Tablas, in the Chapare region (department of Cochabamba, Bolivia).
