Taxonomy Detail

Class Dictyochophyceae

Dictyochophyceae P.C.Silva, 1980: 55.

Type of name: Dictyocha Ehrenberg 1837

Original publication: Silva, P.C. (1980). Names of classes and families of living algae: with special reference to their use in the Index Nominum Genericorum (Plantarum). Regnum Vegetabile 103: 1-156.

Authority notes: Formerly Silicoflagellata

Taxonomic notes:

According to Demura at al. (2009), Hosoi-Tanabe et al. (2007) examined the morphology and phylogeny of C. verruculosa Y. Hara & Chihara 1994 and transferred this species to the Dictyochophyceae and established a new genus, Pseudochattonella (Y. Hara & Chihara) Tanabe-Hosoi, Honda, Fukaya, Inagaki & Sako. They also note that Takano et al. (2007) also placed Chattonella globosa Y. Hara & chihara 1994 in Dictyochophyceae based on their molecular phylogenetic study.
