Common Pellia

<em>Pellia epiphylla</em>, known as the common pellia, is a thallose liverwort in the family Pelliaceae and one of the most frequently encountered bryophytes in temperate regions. It grows in dense, dark-green mats typically found along stream banks, wet rock faces, moist woodland floors, and other persistently damp habitats where it can absorb water directly through its undifferentiated thallus. The species is distributed across Europe, including Belgium, Denmark, Luxembourg, Norway, and Portugal, as well as parts of Asia including Taiwan and North America including the United States, reflecting a broadly circumboreal range. <em>Pellia epiphylla</em> reproduces both sexually, producing distinctive stalked spore capsules in spring, and vegetatively through fragmentation. It is currently assessed as Vulnerable on the IUCN Red List, indicating that populations face moderate risk due to habitat loss and degradation associated with wetland drainage, water pollution, and land-use change. Biological traits such as average lifespan, thallus dimensions, and detailed ecological requirements remain poorly documented compared to vascular plants. The species is ecologically important as a pioneer on disturbed moist soils and contributes to moisture retention in riparian ecosystems.
