|discussion=<p><i>Donnellia commutata</i> is common in oak scrub of north central Florida, but has been mostly overlooked because of its sympatry with and morphological similarity to <i>Sematophyllum adnatum</i>, one of the great weedy mosses. <i>Donnellia commutata</i> may be distinguished satisfactorily only when fertile by its shorter setae, white peristome (when dry), and rather smooth exostome teeth. The endostome often appears absent because the segments break off shortly after the loss of the operculum. However, the endostome can be easily demonstrated by the dissection of mature, operculate capsules.</p>
