Notes: No type specimen has been designated for this taxon. Xu et al. (2010) used sequences from CBS cultures CBS 321.68, CBS 276.69, and CBS 126.13 identified as Sclerotium rhizodes to determine their phylogenetic placement. All three CBS-derived sequences were recovered in a clade closely related to sequences variously identified as Ceratobasidium and Rhizoctonia . Xu et al. (2010) then transferred S. rhizodes to Ceratorhiza with no neotype designated. The transfer of S. rhizodes to Ceratorhiza demonstrates that these cultures and sequences represent a contemporary concept of S. rhizodes / Cr. rhizodes and that transfer of this epithet to Rhizoctonia is justified based on this understanding. Sequences from CBS 321.68 were selected as representative sequences for our analysis.
