|discussion=<p>Species 2 (2 in the flora).</p><!--
--><p>Warnstorfia consists of autoicous species with leaves gradually curved to straight and gradually narrowed to the apex. Clear red pigments occur very rarely in very exposed situations. The alar regions are transversely triangular or isodiametric, and consist of inflated, and (at least when young) usually hyaline cells. Warnstorfia typically occurs in mineral-poor fens, W. fluitans sometimes also in bogs. Although the species are mostly found in nutrient-poor habitats, W. fluitans can stand considerable nutrient-enrichment as evidenced by polluted localities in Europe. Warnstorfia plants with falcate leaves and lacking sporophytes or perichaetia and perigonia can be confused with similar species of Sarmentypnum. The latter, however, frequently develop red pigments, have more sharply delimited transversely triangular alar regions, and are dioicous. In addition, Sarmentypnum is found mostly in intermediately mineral-rich rather than mineral-poor habitats.</p>
