|discussion=<p>The <i>Orthotrichum strangulatum</i> complex contains three species, all endemic to eastern and central North America. These three species all occur as blackish, dense tufts on dry calcareous rock and have similar sporophytes with immersed, oblong, deeply 8-ribbed capsules that are strongly constricted below the mouth when dry. The stomata are found in the distal capsule nearly covered by subsidiary cells, and the endostome segments are fragile. Although often described as one polymorphic species, here plants with 1-stratose, revolute margins are recognized as <i>O. lescurii</i>, those with 1-stratose, plane margins as <i>O. parvulum</i>, and those with multistratose leaf margins as <i>O. strangulatum</i>.</p>
