|discussion=<p><i>Hygrohypnum montanum</i> is most easily recognized by a combination of individually variable features: tiny ovate to ovate-lanceolate leaves with recurved proximal margins, serrulate distal margins, and stem lacking a central strand. Also useful but difficult to see are the few abaxial apical cells that are papillose by anteriorly overlapping end walls. The stems are prostrate to slightly ascending at the apices. The alar cells have incrassate, slightly pitted, yellowish walls.</p>
