|discussion=<p>Orthotrichum stellatum is distinguished by the strongly ribbed, strangulate capsules with well-developed endostomes of eight segments. In comparison, O. ohioense has weakly ribbed capsules that are not constricted below the mouth and an endostome that is lacking or rudimentary. From O. pumilum, the narrowly lanceolate leaves and small laminal cells with unevenly incrassate walls differentiate O. stellatum.</p>
