|discussion=<p>In North America, Hypnum callichroum is frequent only near the Pacific Coast, where it is relatively easy to determine; the shiny plants produce sporophytes in summer. The alar cells are bounded by quadrate to triangular cells distally. The presence of a hyalodermis and the distinct alar region of thin-walled cells that are strongly differentiated from the adjacent cells are reliable characters. However, material without sporophytes can be difficult to determine. Epiphytic specimens frequently have sporophytes, while terrestrial ones generally lack them.</p>
