There are two known species of Reboulia: Reboulia hemisphaerica, which is found in Europe, Asia, and North America, and Reboulia rossica, which is native to Russia and Japan. Reboulia liverworts are small and inconspicuous plants that grow in damp habitats, such as rocks, boulders, and tree trunks. They are often found in shaded areas in temperate and tropical regions.

Appearance
Reboulia liverworts are small plants that grow up to 5 cm in length. They have a flattened, hemispherical shape and are dark green in color. The thallus, or body of the plant, is lobed and has a smooth surface. It is attached to the substrate by rhizoids, which are thread-like structures that absorb water and nutrients from the environment. Reboulia liverworts reproduce asexually through gemmae, which are small, cup-shaped structures that detach from the parent plant and grow into new individuals. They can also reproduce sexually through spores that are released from sporophytes, which are small stalks that grow from the thallus.
