The fungi belonging to the phylum Blastocladiomycota were initially included in a clade that constituted the phylum Chytridiomycota. But recently, on the basis of the results of molecular data and the characteristic of their ultrastructures, they are placed as a sister clade to Zygomycota and Glomeromycota. They can be saprotrophs, and they can exhibit sporic meiosis.
