Distinguishing Features

The rare Scapania ornithopoides is the largest species in the genus, its red-yellow leafy shoots measuring 5+ cm long and up to 5 mm wide as they arch off of peaty slopes in very wet open coastal regions. The leaves have toothed, ellipsoidal and unequal lobes that are unique in showing no obvious point of convergence ("keel"), thus almost appearing as seperate leaves. The lobe tips are gently rounded, not pointed.

Similar species

In its habitat and size, S. ornithopoides could only be mistaken for S. bolanderi, which can grow under shrubs in extremely wet areas. That species, however, has a well developed and plainly visible keel, a feature lacking in S. ornithopoides.

Habitat

Moist to wet, often shady humus, rock outcrops, boulders, cliffs, bogs, fens, streambanks, seepage areas, and heath in the lowland and montane zones

Associated species

Herbertus aduncus, Mylia taylorii, Pleurozia purpurea, Dicranum majus, Dicranodontium denudatum
