|discussion=<p><i>Hygrohypnum molle</i> has been much confused with <i>H. bestii</i> and <i>H. duriusculum</i>, less so with <i>H. alpinum</i>. The essential features of <i>H. molle</i> are the undifferentiated alar cells and broadly ovate, distinctly concave leaves, which taper to an acute, blunt, slightly denticulate apex. In addition, the leaves are essentially straight and loosely imbricate, little differing moist or dry. The stems are procumbent with widely spaced branches that are often as long as the stems.</p>
