|discussion=<p><i>Plagiomnium medium</i> has most often been confused with 2. <i>P. ciliare</i> and 7. <i>P. insigne</i>; see the discussions of those species. The considerable morphological variation within <i>P. medium</i> may also reflect confusion with at least one undescribed species. One British Columbian collection that closely resembles <i>P. medium</i> is dioicous and has larger leaves and laminal cells. The leaf marginal teeth in <i>P. medium</i> are often hooked forward when composed of multiple cells.</p>
