|discussion=<p>The sporophyte of <i>Didymodon ferrugineus</i> is rare and similar to, but often smaller than, that of <i>D. fallax</i>. This species is easily mistaken for the western <i>Triquetrella californica</i>, which, however, is quickly distinguished by its triangular stem section, distal leaf margins sharply crenulate by projecting papillae (but not by projecting cell walls as in <i>D. nigrescens</i>), and distal medial laminal papillae tall, branching from the base, and centered over each lumen. It intergrades with <i>D. fallax</i> to some extent but is usually larger, with broader, ovate-lanceolate leaves that are commonly strongly reflexed (and therefore do not lie flat on a slide), and the papillae may be large and strongly evident. The leaf base is never abruptly ovate as it sometimes is in <i>D. fallax</i>. The peristome is very fragile and often appears missing.</p><!--
--><p>The illegitimate name <i>Tortula</i> recurvifolia (Schimper) Austin has also been used for this species.</p>
