- Genus pilularia includes small liverworts known commonly as pillworts due to the peculiar, round or ellipsoidal sporangium found at the apex of each gametophyte plant.
- Members of genus pilularia tend to have creeping rhizome branches along with well-defined gametophyte plant stems with gemma cups or mucilage-filled involucres around reproductive organs.
- Taxonomically the class and family level positioning of the genus pilularia and family pilulariaceae is classed as belonging to plantae superdivision bryophytina, division bryophyta and subclass jungermanniidae.
- In most studies genus pilularia and pilularia americana have been traditionally separated and there has been a close connection established between these two species of pillworts.
- The main diagnostic characteristic to distinguish genus pilularia is the presence of rhizome gemmae or small round subterranean asexual propagules when viewed under microscopic magnification.
