|discussion=<p><i>Atrichum cylindricum</i> is distributed along the Atlantic and Gulf coastal plain from Virginia to Florida and eastern Texas, and in the Mississippi Embayment and Cumberland Plateau. In addition to the published distribution (Gary L. Smith 1977), the species has also been found on hummocks in a cypress swamp in southern Illinois. <i>Atrichum crispulum</i> is similar in size to <i>A. cylindricum</i>, but is dioicous, with broader, distinctly undulate leaves and well-developed teeth on the back of the lamina. <i>Atrichum altecristatum</i> is a more slender plant with taller lamellae, shorter, broader, undulate leaves, toothed on the back and less strongly bordered, and shorter capsules.</p>
