Corticata ("one with a cortex"), in the classification of eukaryotes (living organisms with a cell nucleus), is a superkingdom suggested by Thomas Cavalier-Smith to encompass the following two eukaryote supergroups:^{[citation needed]}

Plantae,^[1] or Archaeplastida (land plants, red algae, green algae, and glaucophytes)
Chromalveolata (a polyphyletic group including kelp, water moulds, ciliates, dinoflagellates, and other organisms)

Cavalier-Smith later included Rhizaria as well, resulting in a close similarity to Diaphoretickes — not identical as Diaphoretickes does not contain polyphyletic taxa.^[2]^[3]^[4]

The clade comprising Chromista and Plantae was originally called photokaryotes (Cavalier-Smith, 1999) but following a criticism that this misleadingly implied a common photosynthetic ancestry of both groups (which would be untrue if they are sisters as most evidence indicates, but true if chromists were nested within Plantae as a few trees have suggested) it was changed to corticates because both kingdoms have cortical alveoli in one or more phyla (Cavalier-Smith, 2003a; see also 2003b; Cavalier-Smith and Chao, 2003a). However Adl et al. (2012) introduced an entirely unnecessary, and less euphonious third synonym with no intuitive meaning – Diaphoretickes, which is destabilising and should not be used. To stabilise nomenclature we now formally establish superkingdom Corticata to embrace kingdoms Plantae and Chromista (i.e. to mean the same as the vernacular term 'corticates' so either can be used as is appropriate).
