|discussion=<p><i>Ptychostomum rutilans</i> is a distinctive arctic species with dark red shoots, usually forming dense turfs on wet soil. The species is similar to <i>P. pallens</i>, but differs in its incrassate porose laminal cells and reduced peristome. Small specimens are similar to <i>Rosulabryum</i> subelegans, which generally has green-red spirally twisted leaves and mostly grows on rock in alpine regions of northwestern Europe. D. T. Holyoak (2004) considered them the same species because the type of R. subelegans also has 2-stratose borders. They are here kept separate until more detailed studies are completed.</p>
