Chlorophyta families

The Dasycladaceae is one of the two extant families of green algae of the order Dasycladales. When found in Palaeozoic limestones, they typically indicate depositional depth of less than 5m.

Nephroselmidaceae is a family of green algae, the only family in the order Nephroselmidales and the class Nephrophyceae within the division Chlorophyta.

The Eremosphaeraceae are a family of green algae in the order Chlorellales.

Chlorodendraceae is a family of green algae in the order Chlorodendrales.

The Palmophyllales are a deep-branching order of thalloid green alga, containing the single family Palmophyllaceae. They possibly form a sister group to the Chlorophyta. They survive today in deep waters, and can be found at 210 meters below the surface, where predation pressure is reduced. The group contains the genera Palmophyllum, Verdigellas and Palmoclathrus. The morphology of Palmophyllales is unusual in that they are composed of cells in a gelatinous matrix, so they are multicellular, but not in a conventional way.

Pedinomonadaceae is a family of green algae. They are small (less than 3 μm) single-celled algae. Each cell has a single flagellum. Molecular data has provided evidence for an independent class Pedinophyceae (including the Pedinomonadaceae), sister to all phycoplast-containing core Chlorophyta (Chlorodendrophyceae, Trebouxiophyceae, Ulvophyceae and Chlorophyceae).

Mamiellaceae is a family of green algae in the order Mamiellales.

Pseudoscourfieldiaceae, formerly Pycnococcaceae is a family of green algae in the order Pseudoscourfieldiales. The defining features of this family include the single invagination of the pyrenoid where the mitochondrial membrane fits into it and the "decapore" - a ring of 10 pores through the thick cell wall.

Coleochaetaceae is a family of algae. It is the only family in the Coleochaetales, an order of parenchymous charophyte algae, within the class Coleochaetophyceae. It includes some of the closest multicellular relatives of land plants. It contains the genus Coleochaete and questionably includes the fossil genus Parka.
