|discussion=<p><i>Diphasiastrum complanatum</i> forms a hybrid with <i>D. digitatum</i> that is seemingly uncommon and has never received a binomial designation. It is probably far more common than collections indicate, however. Superficially, the hybrid resembles both parents and is often confused with them. Collections are known from Ontario, Quebec, Connecticut, Maine, Michigan, Minnesota, New Hampshire, Vermont, and Wisconsin.</p>
