|discussion=<p><i>Hypnum plicatulum</i> is a predominantly boreal to Arctic species, scattered in the Northern Hemisphere and producing sporophytes infrequently in summer. Useful distinguishing features include the frequently close-pinnate stems, yellowish green to golden green leaves with green to yellow stems, stems with hyalodermis, and auriculate leaves with a few differentiated alar cells that are sometimes excavated. See also discussions under 3. <i>H. callichroum</i>, 10. <i>H. hamulosum</i>, and 11. <i>H. holmenii</i>. Plants of <i>H. plicatulum</i> have branches 0.5–1 mm wide; the leaves have five or six pigmented, thick-walled alar cells, 6–15 µm; and the endostome cilia are as long as the segments.</p>
