Cristidiscoidea is a proposed basal holomycota clade in which Fonticula and Nucleariida emerged, as sister of an unnamed clade in which the Opisthosporida and the Fungi emerged. Since it is close to the divergence between the main lineages of Fungi and Animals, the study of Cristidiscoidea can provide crucial information on the divergent lifestyles of these groups and the evolution of Optisthokont and slime mold multicellularity.
