|discussion=<p><i>Plagiobryum zieri</i> is a predominantly montane-alpine species that is disjunctively distributed between eastern and western North America. The species differs from <i>P. demissum</i> in the julaceous, whitish or silvery green plants that are usually suffused with tinges of pink. <i>Plagiobryum demissum</i> is invariably red or reddish brown, and the shoots are non-terete. The broadly ovate, flat-margined leaves of <i>P. zieri</i> also serve to identify the species. Sterile collections are more likely to be confused with <i>Bryum argenteum</i>, which is also silvery-green and has a similar leaf shape. However, plants of <i>B. argenteum</i> are smaller, have laminal cells firm to ± incrassate distally and quadrate proximally, lack pinkish coloration and occur in drier, often disturbed or nitrogen enriched habitats.</p>
