|discussion=<p>Species 1.</p><!--
--><p><i>Eurhynchiastrum</i> was segregated from the polyphyletic Eurhynchium (M. S. Ignatov and S. Huttunen 2002), where it was placed by most authors. Other authors, such as G. De Notaris (1867), H. Robinson (1987), and K. D. McFarland (1994b), accepted its placement in <i>Rhynchostegium</i>. North American species of <i>Rhynchostegium</i> differ from <i>Eurhynchiastrum</i> in their robust habit and lack of an abaxial spine at the end of the costa. In the present concept, Eurhynchium is strictly a Palearctic genus.</p>
