Chaetopeltidales are an order of green algae in the class Chlorophyceae.[1] In comparison to other chlorophycean orders, the order is species-poor and was circumscribed relatively recently, in 1994; the key ultrastructural features include having zoospores with four flagella, with the basal bodies in a cruciate arrangement.[2]
Members of the Chaetopeltidales consist of unicellular, filamentous, colonial or thalloid algae. Vegetative cells lack plasmodesmata. Chloroplasts have pyrenoids which are sometimes transversed by thylakoids and cytoplasmic channels.[3]
Phylogenetic relationships within the order are as follows:[3]
