Pseudogrinnellia is a genus of red alga in the family Delesseriaceae.
The Prorocentrales are a small order of dinoflagellates. They are distinguished by having their two flagella inserted apically, rather than ventrally as in other groups. One flagellum extends forward and the other circles its base, and there are no flagellar grooves. This arrangement is called desmokont, in contrast to the dinokont arrangement found in other groups. Accordingly, the Prorocentrales may be called desmoflagellates, and in some classifications were treated as a separate class Desmophyceae.
Ulvales is an order of green algae.
The Fucales (fucoids) are an order in the brown algae. The list of families in the Fucales, as well as additional taxonomic information on algae, is publicly accessible at Algaebase.
Navicula is a genus of boat-shaped diatom algae, comprising over 1,200 species. Navicula is Latin for "small ship", and also a term in English for a boat-shaped incense-holder.

Pedinophyceae is a class of green algae in the division Chlorophyta.
The Trebouxiophyceae are a class of green algae, in the division Chlorophyta. Their circumscription within the green algae is not well established due to the need for more genetic studies at higher levels within the group.
Chaetophorales is an order of green algae in the class Chlorophyceae.
Cryptomonadales is an order of Cryptophyta containing the families Cryptomonadaceae and Hilleaceae.
The Gymnodiniales are an order of dinoflagellates, of the class Dinophyceae. Members of the order are known as gymnodinioid or gymnodinoid. They are athecate, or lacking an armored exterior, and as a result are relatively difficult to study because specimens are easily damaged. Many species are part of the marine plankton and are of interest primarily due to being found in algal blooms. As a group the gymnodinioids have been described as "likely one of the least known groups of the open ocean phytoplankton."
Botrydiaceae is a family of yellow-green algae comprising 13 species in three genera. It is the only family in the order Botrydiales.
Oxyrrhis is a genus of dinoflagellates. It includes the species Oxyrrhis marina.
Perkinsidae is a family of alveolates in the phylum Perkinsozoa, a sister group to the dinoflagellates.
Mamiellophyceae is a class of green algae in the division Chlorophyta.
Pyramimonadophyceae is a class of green algae in the division Chlorophyta.
Syracosphaerales is an order of algae consisting of three families:
