Distinguishing Features
Common in rare habitat, Odontoschisma elongatum presents itself on inorganic creek banks of very wet, boggy regions as a dark green-brown, reclined shoot of intermediate size (~2 mm wide by 1-3 cm long). The rounded, saucer-shaped leaves are arranged suboppositely and point towards the shoot tip. Underleaves are small, triangular and relatively inconspiculous.
Similar species
Could be mistaken for Syzygiella autumnalis, which occurs in the same habitat but has flat leaves and lacks an underleaf. Other round-leafed species of Odontoschisma are upright and have larger underleaves (O. macounii) or more colourful pigmentation (O. denudata), whereas O. elongatum as reclined shoots with dark pigmentation and barely perceptable underleaves.
Habitat
Moist to mesic humus, cliffs, ledges, crevices, peatlands, swamps, bogs, streambanks, waterfall spray zones, and tundra in the lowland, montane, and subalpine zones.
