Chloropicophyceae is a class of green algae in the division Chlorophyta that, along with Picocystophyceae, coincides with the traditional "prasinophyte clade VII".[1]

Description

Members of this class are coccoid green cells, with a diameter of 1.5–4 µm, found in marine waters, with one nucleus, one mitochondrion, and one chloroplast surrounded by two membranes, containing starch grain; their single chloroplast has chlorophylls a and b; they lack pyrenoid and flagella; and they have a layered cell wall. Their sexual reproduction is unknown.[1]

Taxonomy

In total, this class contains eight newly described species, belonging to two genera. The taxonomy goes as follows[1] :

Phylogeny

In the 2017 article where the new class is described, it is shown as the sister clade of the class Picocystophyceae. The internal relationships are shown in the tree below, which is a simplified version of the phylogenetic tree elaborated in the research:[1]
