The most recent classification scheme of protists supports early observations that endoparasitic, net, and acrasid slime molds are distantly related to the other slime molds, with Peronosporomycetes and Labyrinthulomycetes being placed in Chromalveolata: Stramenopiles, and the Acrasidae assigned to Excavata: Heterolobosea (Adl et al., 2005). Plasmodial, cellular, and protostelid slime molds are thought to be closely related, with current classification assigning them all to Amoebozoa: Mycetozoa
(Adl et al., 2005).
