Distinguishing Features
An occasional species that becomes increasingly prominent in moist microhabitats, this dull green liverwort with elongate leaves made up of unequal lobes forms scrambling stems over tree trunks and in rock crevices. It stands out on account of its matte texture, with the pointed lobe tips and long triangular form of said lobes making it unique among other unequally-lobed liverworts.
Similar species
The elongate pointed lobes of Douinia are distinct from the rounded lobes of Scapania and the blunt tips on the lobes of Diplophyllum and Macrodiplophyllum.
Habitat
Tree trunks (both deciduous and coniferous), humus, rock outcrops, boulders, cliffs, decayed wood, and bogs in the lowland and montane (rare) zones; frequent in coastal BC; rare in se BC [Mica Creek].
Associated species
Frullania sp., Ulota sp., Metzgeria sp.
