|discussion=<p>Although typically considered a variety of <i>Bryum argenteum</i>, <i>B. lanatum</i> from western North America and other parts of the world is quite distinctive. However, the type of <i>B. lanatum</i> from Europe may be a form of <i>B. argenteum</i>, in which case a new name will be needed. The species is characteristic of undisturbed native plants communities and is especially common in semiarid parts of the West on dry soil; capsules are rare. <i>Bryum argenteum</i> generally grows in more moist climates in highly disturbed sites, especially where there is excess nitrogen. The distribution of <i>B. lanatum</i> in the eastern part of North America is not well understood because the species has been combined with <i>B. argenteum</i> by bryologists of that region.</p>
