In North America, Pseudoscleropodium purum has become a common lawn moss in southwestern British Columbia and nearby parts of Washington State. It has been observed in Saint John's, Newfoundland, in a park lawn, and in Ann Arbor, Michigan, in a field adjacent to an arboretum. These stations are consistent with the weedy status of the species in North America.
The precise original range of this feather moss has not been ascertained, but it appears to be native from central Europe, northwestward and westward to southern Fennoscandia and Britain and Ireland. There is general agreement that its occurrence on certain islands (Hawaii, Sri Lanka, Réunion, St. Helena, Tristan da Cunha, Azores), in North America, and the Southern Hemisphere (Chile, New Zealand) is the result of inadvertent introduction, most likely from plants employed as packing for china and nursery stock shipped from Europe or elsewhere.
