Rhytidiadelphus triquetrus, the big shaggy-moss[1] or rough goose neck moss,[2] is species of moss in the family Hylocomiaceae. It is often the dominating moss species in moderately rich forest habitats in the boreal regions and the Pacific Northwest. Because of its fuzzy appearance and tail-like shape it is also called the 'electrified cat's tail moss'.[3] Not to be confused with square goose-necked moss, Rhytidiadelphus squarrosus.


Terrestrial on humus-rich substrates in montane forests. Occasionally grows on logs and trees in lowland rainforests or on sandy-gravelly soils near streams.[3]
