|discussion=<p><i>Cynodontium schisti</i> is distinctive in having undivided peristome teeth that may be perforated. <i>Cynodontium alpestre</i> and <i>C. glaucescens</i> are reported also with poorly divided teeth, commonly divided in the distal 1/4 or to near the middle, whereas all other species of the genus have teeth typically divided to the middle or reaching to nearly the base. If the division of the peristome is part of a transformation series involving <i>Cynodontium</i> and the segregate Cnestrum, then <i>Cynodontium schisti</i> would represent the end-member, with peristome undivided. The operculum is only obliquely conical, rather than the long-rostrate operculum typical of <i>Cynodontium</i>. The cell lumen shape in leaf cross sections is more regularly quadrate rather than distorted-mammillose, and the cells generally have the low, rounded papillae of papillose mosses such as those of the <i>Pottiaceae</i>. The presence of similar quadrate (nonmammillose) lumina in section in <i>C. alpestre</i> and <i>C. glaucescens</i> should be looked for.</p>
