|discussion=<p><i>Hygrohypnum cochleariifolium</i> is rare in the flora area and documented by eight examined specimens; these specimens come from the far north or as disjunctions south along the Rocky Mountains to Colorado. The species may be recognized by the following character combination: small leaves, usually less than 1 mm; leaf shape varying from ovate to broadly ovate to ovate-elliptic with generally recurved margins; costa usually short and double; and alar cells essentially undifferentiated. Most distinctive is the leaf concavity; no other species in the genus has leaves so deeply concave. The plants grow in loosely woven, easily fragmenting, often silt-clogged patches or small, tightly woven patches; the leaves may be crowded or very distant, with regularly cucullate apices.</p>
