|discussion=<p><i>Orthotrichum pylaisii</i> is distinguished by the ribbed capsules with reflexed exostome teeth and a rudimentary endostome, along with superficial stomata and large, ovate-lanceolate leaves. The capsule is usually exserted in North American populations; however, in European populations it is sometimes only emergent.</p>
