|discussion=<p>Variety humile is easily recognized by a much shorter costa than has been associated with other names included within <i>Hygroamblystegium varium</i>, more elongate laminal cells, and undifferentiated alar cells. The length of the costa is, however, a plastic character that varies depending on water availability; in North America in particular, many specimens display a costa that ranges from ceasing at mid leaf to subpercurrent, rendering the distinction with other taxa within <i>H. varium</i> difficult. Variety humile often exhibits a complanate habit, which explains why the taxon has sometimes been associated with <i>Leptodictyum</i>, but this character also strongly varies, and molecular data unambiguously show that the taxon is nested within <i>Hygroamblystegium</i>. Variety humile also bears strong resemblance to <i>Pseudocampylium radicale</i>, from which it is distinguished by non-decurrent leaves.</p>
