|discussion=<p><i>Campylopus introflexus</i> occurs in masses in sand dunes along the west coast of North America and throughout the Southern Hemisphere. The species was introduced in Great Britain in 1942, and since the beginning of the 1970s has been aggressively spreading through Europe. It now ranges from Iceland to Spain and from Ireland to Poland. The first record in North America dates from August, 1975, and was made on a gravel roof of a building of Humboldt University, Arcata, California. The species is undoubtedly introduced in North America and is spreading here as rapidly as in Europe. The name <i>C. introflexus</i> was used previously for <i>C. pilifer</i>, thus all old references for <i>C. introflexus</i> in North America have to be referred to that species. Also, specimens of <i>C. surinamensis</i> and <i>C. oerstedianus</i> from North America were named as <i>C. introflexus</i>. <i>Campylopus introflexus</i> is easily recognized by the reflexed hair points. Female plants have terminal perichaetial buds. Problems may rarely arise with forms from shaded habitats, in which the hairpoints are absent or so short that they are not reflexed.</p>
