genus in the family Marchantiaceae of the order Marchantiales, a group of liverworts. The Marchantia shows differentiation into two layers: an upper assimilatory region and a lower storage region with a well-defined upper epidermis with air channels . The thallus features tiny cup-like structures called gemmae cups, which are used for asexual reproduction. The combination of barrel-shaped pores and gemmae cups are diagnostic of the genus. Multicellular purple colored scales with single cell thickness and unicellular rhizoids are present on the ventral surface of the thallus.
