|discussion=<p><i>Calliergon cordifolium</i> is most frequently confused with the dioicous <i>C. giganteum</i> when the latter species does not form its characteristic miniature sprucelike shoots. Both species have alar regions that reach or almost reach the costa, but whereas <i>C. cordifolium</i> has diffusely delimited groups and a stem leaf costa that is 54–117(–133) µm wide near its base, <i>C. giganteum</i> has sharply delimited alar cells and a costa that is (88–)95–282 µm wide. <i>Calliergon cordifolium</i> is never pale pink, like some expressions of <i>C. giganteum</i>; finally, <i>C. cordifolium</i> tends to grow in more nutrient-rich and slightly less mineral-rich habitats than the latter. For differences with 2. <i>C. orbicularicordatum</i>, see the discussion of that species.</p>
