Corticata

Herbarium specimen of Gastridium articulatum, from University of California, Berkeley.


Belongs within: Eukaryota.
Contains: Vendophyceae, Hacrobia, Harosa, Glaucophyta, Rhodophyceae, Chlorophyta, Streptophyta.

The Corticata is a clade of eukaryotes supported by molecular phylogenies that might be described as comprising the major algal lineages and related taxa. Cavalier-Smith et al. (2015) defined this clade as including all descendents of the common ancestor of Arabidopsis and Paramecium. Many members of this clade are photosynthetic; members of the subclade Plantae possess chloroplasts with chlorophyll a as the primary pigment that is believed to have arisen through a single primary endosymbiosis with a cyanobacterium. Photosynthetic members of the sister subclade, labelled Chromista by Cavalier-Smith (2010), usually have a chlorophyll c-containing chloroplasts that arose through secondary endosymbiosis with another photosynthetic eukaryote; debate continues, however, as to whether there was a single such event near the base of the chromist clade (followed by multiple chloroplast losses) or whether the various photosynthetic chromist lineages acquired their chloroplasts independently.

Fossil macroscopic algae have also been assumed herein to belong within the Corticata, though the true relations of groups such as Vendophyceae and Chuariaphyceae to modern multicellular algae remain uncertain.

Characters (from Cavalier-Smith et al. 2015): Eukaryotes ancestrally with ventral feeding groove and cytoskeleton comprising single dorsal centriolar microtubular root and dorsal fan, posterior split right root with I fibre and left root with C fibre, and intermediate single root; cortical alveoli often present; ciliary hairs often not associated with latticed paraxonemal rod.
