|discussion=<p>In the flora area, <i>Didymodon anserinocapitatus</i> is known only from Colorado and New Mexico (R. H. Zander and W. A. Weber 1997). The arctic species <i>D. johansenii</i> is similar in the swollen, deciduous apex, but differs mainly by its distal laminal cells 13–15 µm wide, and guide cells in only a single layer. <i>Didymodon rigidulus </i>var.<i> icmadophilus</i>, a widespread montane taxon, is similar in appearance but its leaf apices are never swollen though sometimes fragile. The American material differs from the Asian type (China: Tibet, Nan Xian, Zang Mu 1704, isotype–NY) in being less robust, the leaves reaching only 1.8 mm, and the proximal cells quadrate to short-rectangular (leaves to 2 mm and proximal cells to 4:1 in the Asian specimen).</p>
