|discussion=<p><i>Grimmia elongata</i> is a widely distributed species mainly occurring above 2000 m, and with a preference for acidic sandstones and volcanic, damp, north-facing outcrops and ledges. It seems to be uncommon in North America, having been collected only occasionally and from widely separated localities. However, the wide distribution of <i>G. elongata</i> across the Northern Hemisphere suggests that it may be more common on this continent than collection records indicate. Cao T. and D. H. Vitt (1986b) noted that in North America, specimens of <i>G. elongata</i> would be confused most likely with <i>G. donniana</i>, as they considered the two species to be closely related. However, these species are distinctly different in a number of clear characters: <i>G. elongata</i> is reddish brown, muticous or short-awned, has one leaf margin recurved and is dioicous. In contrast, <i>G. donniana</i> is green to black, long-awned, has plane leaf margins and is autoicous. These characters lead us to believe that these species are not closely related; H. C. Greven (2003) believed that <i>G. elongata</i> is most closely related to the Himalayan endemic G. redunca Mitten.</p>
