|discussion=<p><i>Hygrohypnum styriacum</i> is distinctive but sometimes mistaken for small, falcate-leaved forms of <i>H. luridum</i>. The two species are sympatric in western North America. Leaves of <i>H. styriacum</i> are ovate to slightly broadly so, with an abruptly acuminate apex. Leaves of small, falcate-leaved specimens of <i>H. luridum</i> taper gradually to an acute apex from an ovate or oblong-lanceolate base. The costa of <i>H. styriacum</i> is subtly slightly stouter than that of <i>H. luridum</i>. All leaves of <i>H. luridum</i> have a well-developed region of quadrate, short-rectangular, or irregular alar cells; alar regions of <i>H. styriacum</i> are undifferentiated or composed of few quadrate or short-rectangular to irregular cells that grade imperceptibly into adjacent cells. A differentiated annulus may be found upon lifting the operculum of <i>H. styriacum</i>, while such an annulus is absent in <i>H. luridum</i>.</p>
