Cephaloziaceae is a family of liverworts.

Liverworts of this family are dioecious plants which have creeping or upright forms. They are green, brown, reddish, or purplish in color. The leaves are alternately arranged and succubous. Oil bodies are rare. They reproduce sexually, or vegetatively via gemmae.^[1]

There are about 13^[2] to 16^[1] genera in this family.

They include:^[3]

• Alobiella
• Alobiellopsis^[4]
• Anomoclada
• Cephalozia
• Cladopodiella
• Fuscocephaloziopsis
• Haesselia
• Hygrobiella
• Iwatsukia^[5][6]
• Metahygrobiella^[7]
• Nowellia
• Odontoschisma^[8]
• Pleurocladula
• Schiffneria
• Schofieldia
• Trabacellula

Family Cephaloziaceae is frequently rearranged. For example, genetic analysis suggests that genus Hygrobiella should be moved out of the family, and perhaps classified in a family of its own,^[9] and microscopic analysis of the morphology of Trabacellula also suggests it should be separated and made into a new family.^[10]
