Odontoschisma sphagni (Odontoschisma sphagni)
Description
O. sphagni is the commonest liverwort with unlobed, round leaves held upright from the stem (rather than flat like a Calypogeia) that grows in bogs. O. sphagni is usually characteristically orange, although it may be brown or (rarely) entirely green. Shoots grow up to 3 mm wide and 8 cm long, with leaves a little over 1 mm long and wide. Its leaves have a border of small, thick-walled cells, visible through a -20 hand lens. Abundant, thread-like branches with tiny leaves stick downwards from the stem into the substrate. Fertile plants are uncommon and gemmae are absent.
