|discussion=<p><i>Schistidium crassithecium</i> is one of the most easily recognized species of the genus. Even though usually sterile, its thick leaf margins, appearing club-like in transverse-section, but resembling marginal curvatures macroscopically, and the fleshy apiculi that terminate the leaves are distinctive characters. The fleshy apiculus, its laminal areolation, and features of the sporophytes appear to relate this species to <i>S. cinclidodonteum</i> and <i>S. occidentale</i>.</p>
