|discussion=<p><i>Hypnum curvifolium</i> might be confused with <i>H. lindbergii</i>; it differs in its more plumose branching, more circinate leaves, and lack of stem hyalodermis. Also, <i>H. lindbergii</i> has a more extensive and often decurrent alar region. <i>Hypnum imponens</i> is distinguishable by its usually smaller habit size and toothed pseudoparaphyllia. <i>Hypnum curvifolium</i> has stems 0.5–3 mm wide; the leaves are curved to the insertion with enlarged, hyaline alar cells; the supra-alar cells are ovoid to triangular and smaller than the alar cells; the laminal cells are sometimes projecting abaxially at the distal ends; the capsules are plicate when dry; and the endostome cilia are nodulose. Sporophytes are produced in summer.</p>
