Discussion
Hypnum plicatulum 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. H. callichroum, 10. H. hamulosum, and 11. H. holmenii. Plants of H. plicatulum 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.
