|discussion=<p>Plagiomnium rostratum is characterized by its small size, often retuse or emarginate leaf apices, not or weakly decurrent leaves, small, blunt marginal teeth, and, in fertile collections, long-rostrate opercula. Plants are commonly observed as masses of sterile stems growing closely to the substratum.</p>
