|discussion=<p><i>Ptychostomum schleicheri</i> is an arctic-alpine species. When well developed, the plants are distinctively large, with long stems, and crowded, yellowish, somewhat imbricate leaves. Much material named <i>P. schleicheri</i> appears to be misidentified and can be referred to <i>P. turbinatum</i>. This species is atypical for <i>Ptychostomum</i> and shows some morphological similarities to Mniaceae, especially in the lack of tmema cells in the rhizoidal filiform gemmae, extremely wide laminal cells, and pronounced shelflike leaf base that remains attached to the stem after the leaf is removed. <i>Ptychostomum subneodamense</i> is similar but has a 1-stratose border, usually contorted and shrunken leaves when dry, and much smaller laminal cells.</p>
