Cephalozia lunulifolia


Cephalozia lunulifolia is a leafy-liverwort that is common to New Brunswick. As with all Cephalozia species, it is tiny (0.5-1.0 mm wide), has bilobed leaves, and has a layer of inflated, transparent cells (an hyalodermis) surrounding the stem. It differs from other Cephalozia species in that the leaves are decurrent, inserted obliquely, and that the lobe tips end in a point that is 1-cell long and 1-cell wide; other species in the genus tend to have tips that are 2-3 cells long and 1 cell wide, are inserted transversely, or are not decurrent. The species name lunulifolia likely referse to the lunate (crescent-moon shaped) sinus between the two leaf lobes.

Habitat and Distribution

Cephalozia lunulifolia can be found on rotting logs, stumps, over peat and humus in bogs and swamps, soil, and rock in moist forests. It is present in all 15 New Brunswick counties, but is small and easily overlooked; there are 21 primary taxon records at New Brunswick Museum, but over 60 associate taxon records.
