Corticata

Corticata ("one with a cortex"), in the classification of eukaryotes (living organisms with a cell nucleus), is a group suggested by Thomas Cavalier-Smith to encompass the eukaryote supergroups of the following two groups:

• Plantae, 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.
