Distinguishing Features

A perplexing species with a reddish hue, Cephaloziella rubella has very narrow (~1/4 mm) leafy shoots. Under the hand lens, you should see leaves divided to about half their length with sharp lobe apices and smooth margins. Vegetative shoots should be completely devoid of underleaves and the antheridia and archegonia (when present) should be close to one another on the same shoot.

Similar species

See notes under C. divaricata, the species it is most likely to be confused for. That species has underleaves on its vegetative shoots and antheridia and archegonia are found on seperate plants, whereas in C. varians underleaves are present on vegetative shoots and archegonia and antheridia are found on the same shoots.

Habitat

Dry to moist humus, decayed wood, cliffs, and rock outcrops in the lowland and montane zones; rare in coastal and sc BC.
