Phycolepidozia exigua was thought to be the only species of liverwort in the genus Phycolepidozia and family Phycolepidoziaceae. Until another species was found. Phycolepidozia exigua is endemic to Dominica, where it is critically endangered.[1] Its natural habitat is subtropical or tropical moist lowland forests.

The species is unique among the leafy liverworts in the extreme reduction of its lateral leaves.[2] These leaves consist of only two cells at maturity, so that plants are essentially leafless.[3]

In 2014, a new species from India, Phycolepidozia indica Gradst., J.-P.Frahm & U.Schwarz was published and described.[4]
