|discussion=<p><i>Orthotrichum pulchellum</i> is distinguished from all species of <i>Ulota</i> by its glabrous calyptrae and immersed stomata, and from <i>O. consimile</i> by the 16 reddish exostome teeth that are papillose-reticulate with slender, high papillae, and stomata always located at or beyond mid capsule. Also, plants of <i>O. pulchellum</i> are rarely longer than 1 cm, and capsules are usually barely exserted and oblong-cylindric.</p>
