|discussion=<p><i>Tortula systylia</i> may be confused with <i>Stegonia</i> but the latter has a distinct triangle of echlorophyllose cells at the apex of the much broader leaves. It is similar also to <i>T. hoppeana</i>, but the laminal cells are smooth. After dehiscence, the systylius capsules retain a raised operculum on the columellar stalk.</p>
