|discussion=<p><i>Brachythecium rutabulum</i> is a large forest moss forming rather dense, shiny mats with many crowded sympodial branches. Its robust stature and the frequent presence of sporophytes with rough setae often allow for confident field identification. <i>Brachythecium rivulare</i> is equally robust, but can be distinguished in the field by the somewhat dendroid appearance; the sympodial shoots in <i>B. rivulare</i> are usually only slightly branched proximally. Under a microscope, the distinctive inflated alar cells readily separate <i>B. rivulare</i> from <i>B. rutabulum</i>. Alar cells in <i>B. rutabulum</i> have a quite different appearance: they are enlarged in a group just proximal to decurrencies, whereas close to marginal cells, they are narrow and chlorophyllose. More slender plants of <i>B. rutabulum</i> are easy to confuse with <i>Sciuro-hypnum curtum</i> (see discussion under 10. <i>S. curtum</i>).</p>
