|discussion=<p>Hygrohypnum subeugyrium may not truly belong in the genus. The species can be identified by the combination of dark pigmentation, alar differentiation, and leaf tip morphology. Except for stem and branch tips, the older extremities of H. subeugyrium are darkly pigmented reddish brown, reddish black, or brownish black. The transition from the yellow-green stem and branch tips to the darker, older extremities can be quite abrupt. Alar differentiation is clear but variable even among leaves on the same axis. The alar regions may form an irregular group of quadrate or short-rectangular, strongly incrassate, yellowish or reddish brown cells, or a basal row of enlarged, incrassate cells surrounded by a few that are quadrate or short-rectangular; both alar expressions may be excavated. Such alar cells are clearly different from the regularly inflated alar cells of H. eugyrium. Hygrohypnum subeugyrium is most easily recognized by the regular occurrence of a few leaves with abruptly acute apices that are minutely denticulate to finely serrulate among other leaves with entire apical margins.</p>
