Rhytidiadelphus loreus, also commonly known as Lanky Moss, is a nonvascular "feather moss" species that is a key component of a healthy, thriving forest ecosystem. Lanky Moss grows in North America, Canada and Europe. It is primarily a coastal species that grows in moist, coniferous forests. It grows on decaying logs, the forest floor and as an epiphyte on living trees. Its key function is nitrogen fixation, water retention and temperature insulator.
