|discussion=<p><i>Bryum oblongum</i> is distinguished from the closely related <i>B. blindii</i> by the shorter laminal cells of the innovation leaves. A. J. Shaw (1981) enumerated other differences, including generally shorter exostome teeth in <i>B. oblongum</i> (300–400 µm) against longer teeth in <i>B. blindii</i> (400–500 µm). Recently, small, sterile, brownish, julaceous plants from alpine areas of New York have been collected that are similar to <i>B. oblongum</i>, but they have a strongly bulging reddish costa and shorter laminal cells. These collections are likely to represent an undescribed species.</p>
