|discussion=<p><i>Leptodontium flexifolium</i> is a rare species found in rocky places at higher elevations in the southern Appalachians and in the southwestern states. The gemmae that are commonly found on stalks in leaf axils elsewhere were not seen in the flora area. The dentate, bordered leaves are immediately diagnostic of this species, while the anatomical characters of the genus will confirm the identification. Subfossils 40,000 years old have been found (J. A. Janssens and R. H. Zander 1980) at a site in the Yukon. <i>Dichodontium pellucidum</i> is commonly mistaken for this species, but is easily distinguished by the dentate distal abaxial surface of the costa. <i>Barbula convoluta</i> is also similar but has quadrate adaxial costal cells and a distinct stem central strand.</p>
