Trichocolea tomentella is a species of liverwort belonging to the family Trichocoleaceae. It forms loose, pale green to yellowish-white mats and is characterised by its highly divided leaves that give it a feathery or fuzzy appearance. The species has a wide distribution across temperate regions of the Northern Hemisphere, particularly in oceanic and suboceanic areas, occurring in Europe, Asia, North Africa, and eastern North America. It typically grows in moist, shaded locations, especially near springs and streams in deciduous and coniferous forests. While capable of sexual reproduction, with male and female structures on separate plants, it reproduces predominantly through vegetative means via branching and fragmentation. The species shows considerable morphological variation between populations but maintains stable taxonomic characteristics in its cell structure. Though it can form extensive pure patches and effectively compete with other bryophytes in suitable habitats, T. tomentella faces threats from habitat destruction, particularly through logging and drainage of its preferred moist forest habitats.
