Marchantiaceae
Marchantiaceae is a family of liverworts in order Marchantiales. It contains a single genus Marchantia.

Genera in Marchantiaceae 
Until recently, three genera were included in the Marchantiaceae:
 Bucegia Radian 1903
 Marchantia Linnaeus 1753
 Preissia Corda 1829 non Opiz 1852

However, the genera Bucegia and Preissia have since been merged into Marchantia, leaving only the single genus in the family.

 Dumortiera, now in family Dumortieraceae 
 Lunularia, now in family Lunulariaceae
