Opisthosporidia

Opisthosporidia (granting True Fungi) or Fungi are a sister clade of the Cristidiscoidea together forming the Holomycota. A basal group is the 'basal clone group 2' (BCG2).[2][3] The other basal Opisthosporidan clade are the Aphelida together with the True Fungi, joined with the 'basal clone group 1' (BCG1) together with the Rozellomyceta.[1][4][5][6] Historically, the True Fungi were not considered to have emerged in the Opisthosporidia, i.e. was not considered to be a descendant of the last common ancestor of Aphelida and Cryptomycota.
