Algae in the family Prasiolaceae consist of thalli with blades a single cell thick (i.e. monostromatic). Vegetative cells are polygonal with two to four cells arranged within a parent cell wall. Each cell has a single, stellate chloroplast and a central pyrenoid.[4]
Traditionally, it was the only family in the order Prasiolales.[5] However, molecular phylogenetics have shown that additional algae with simple morphologies, such as Stichococcus, also belong to the same clade as this family.[6]

Another, older study places Prasionella as sister to Rosenvingiella.[5] The above cladogram excludes the genus Schizogonium, which is taxonomically problematic and likely a synonym of Rosenvingiella.[8]
