|discussion=<p><i>Polytrichastrum papillatum</i> is known in North America from a single, sterile collection from southern Alaska (Valdez), collected by F. J. Hermann, but is possibly more widespread and overlooked. The marginal cells of the lamellae are coarsely papillose, and resemble those of <i>P. alpinum</i> in section. In profile, however, the lamellae are crenate, the marginal cells crowned by a papillose knob. The exothecial cells with a pale but distinct thin spot in the outer wall further distinguish this species from <i>P. alpinum</i>.</p>
