|discussion=<p><i>Leskea gracilescens</i> is the most common species of the genus in North America. While the species occurs throughout the United States and Canada from North Dakota to Ontario south to the coastal plain, it is most common in the Midwest where its colonies are often quite large and dense. In the western part of its range, plants with blunt leaves are difficult to distinguish from <i>L. obscura</i>. However, these blunt-leaved forms will have some leaves with plications and revolute margins. If mature capsules with intact peristomes are present, <i>L. gracilescens</i> is easily distinguished from <i>L. obscura</i> by an endostome and exostome nearly equal in length (0.2–0.4 mm) and an operculum that is more pointed than the operculum of <i>L. obscura</i>. The plants of <i>L. gracilescens</i> are rigid.</p>
