 The subkingdom Blastocladiomyceta covers a single phylum (Blastocladiomycota), introduced based on phylogenies and divergence time estimates (Tedersoo et al. 2018). It was found and reported as saprotrophs or parasites on plants, animals, and fungi. Morphological descriptions were given by James et al. (2006) and Tedersoo et al. (2018). The phylum Blastocladiomycota contains one subphylum (Blastocladiomycotina) and two classes (Blastocladiomycetes, Physodermatomycetes) (Tedersoo et al. 2018). Thirty-five species are named in Index Fungorum (2023).

Type genus: Blastocladia Reinsch.
