|discussion=<p><i>Leucodon andrewsianus</i> differs from the similar, slightly more robust <i>L. brachypus</i> most evidently in the common presence of tufts of tiny branchlets congested in axils of distal leaves and at branch apices; in some specimens of <i>L. andrewsianus</i>, the branch apices and entire older plants transition into branchlets. The branchlets are mostly very short but sometimes much elongated. In the absence of branchlets, the slender, elongate (35–60 µm) terminal cells of young leaves are helpful for identification of <i>L. andrewsianus</i>. Sporophytes of <i>L. andrewsianus</i> are unknown, and gametangia are extremely rare. Reproduction and dispersion are doubtless accomplished by the caducous branchlets. This taxon has been treated in the flora area as L. sciuroides (Hedwig) Schwägrichen, a moss that occurs in Africa, Asia, and Europe, but apparently not in North America.</p>
