|discussion=<p><i>Orthotrichum alpestre</i> is distinguished by the highly papillose distal laminal cells; slightly twisted, sharply pointed leaves; calyptra with papillose hairs; absence of prostome; and papillose or papillose-reticulate exostome. The endostome is always present in mature capsules and, because of enlarged cross walls, has a shiny appearance. The capsule is usually oblong and strangulate, although the shape depends on age. In some specimens, the capsule is short-cylindric and not much constricted below the mouth. The stomata are found just below mid capsule.</p>
