|discussion=<p><i>Gemmabryum violaceum</i> is distinguished by the combination of violet rhizoids and small, spheric, red to purple-red or orange rhizoidal tubers. <i>Gemmabryum ruderale</i> is similar but has larger tubers, and European material at least has strongly papillose rhizoids compared to relatively smooth rhizoids of <i>G. violaceum</i>.</p>
