|discussion=<p><i>Brachelyma subulatum</i> differs from <i>Fontinalis</i> by its costate leaves and cucullate calyptrae. Usually the presence of costae is enough to identify <i>B. subulatum</i>, but costal expression in <i>Brachelyma</i> is sometimes variable and appears environmentally induced. It is not unusual to find plants with keeled, strongly costate proximal leaves but concave, ecostate or weakly costate apical leaves. <i>Brachelyma subulatum</i> has been noted as lacking an annulus; in fact it has a massive, persistent annulus similar to those in many genera of Hookeriales. <i>Dichelyma</i> differs from <i>B. subulatum</i> in having longer setae and larger calyptrae that cover the capsule and often clasp the distal seta. <i>Brachelyma subulatum</i> appears to be a weak segregate of <i>Dichelyma</i>. <i>Brachelyma subulatum</i> differs from many other aquatic or semi-aquatic mosses in its keeled-conduplicate leaves.</p>
