|discussion=<p>A small, attractive species, <i>Fissidens amoenus</i> can be recognized by its distinct laminal cells, crenulate-serrulate leaf margin, large, more or less oblong, pellucid cells in the proximal parts of the vaginant laminae, and weak limbidium restricted to the proximal parts of the vaginant laminae of perichaetial leaves. The laminal cells have been described as “inconspicuously 1-papillose” (H. A. Crum and L. E. Anderson 1981, as <i>F. hallii</i>), but since that condition is not always present it is perhaps best to regard these cells as strongly bulging.</p>
