'''Corticata''' ("one with a cortex"), in the [classification](/source/Taxonomy_(biology)) of [eukaryote](/source/eukaryote)s (living organisms with a [cell nucleus](/source/cell_nucleus)), is a superkingdom suggested by [Thomas Cavalier-Smith](/source/Thomas_Cavalier-Smith) to encompass the following two eukaryote supergroups:{{citation needed|date=July 2025}}

| quote      = 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).
