Synonym: Prionolobus turneri
Special Status: None.
Recognition: The small size of this liverwort, with its dentate, bilobed leaves, and habitat on mineral soil, makes it easy to learn to recognize by handlens observation.
Distribution: Grows on bare, mineral soil, often on road cuts and trail cuts; only rarely does it occur on wood. Presently known only from western Oregon.
Comments: Cephaloziella turneri is the most easily recognized species of Cephaloziella in North America by its robustness and prominently dentate leaves. It is undoubtedly more abundant now than in the previous century beause of its affinity for the disturbed soil of trail and road cuts where it often forms large colonies. Cephaloziella turneri is a characteristic member of coastal ecosystems. It is found inland, also, but is not nearly as abundant in the Cascades as the Oregon Coast Range.
