Octoblepharum albidum is a weedy and conspicuous moss that is distributed worldwide in the tropics. It grows especially on palms, often forming deep soft cushions. The flat, glossy, ligulate, spreading-recurved leaves distinguish it easily in the field from the superficially similar Leucobryum, which has erect or spreading, pointed, subtubulose leaves.
