|discussion=<p><i>Orthotrichum pellucidum</i> is distinguished by its blunt, lanceolate-oblong leaves that always appear glaucous because of the large 2-fid papillae of the distal laminal cells. When the plants are fertile, which is usually the case, the short-exserted, oblong-ovate, 8-ribbed capsules identify <i>O. pellucidum</i>. The capsule has stomata in the proximal to mid capsule, more or less covered by projecting subsidiary cells.</p>
