Blastocladiomycetes
English: Blastoclads; Chytrids.
Taxonomy
Originally the order Blastocladiales erected by Petersen and classified in the Chytridiomycota. Molecular and zoospore ultrastructural characters showed it was not monophyletic with Chytridiomycota. Members of Blastocladiomycetes though, are often referred to colloquially as Chytrids. However Chytrid should refer only to members of Chytridiomycota.
Members of Blastocladiomycota, Chytridiomycota, and Neocallimastigomycota are lumped together as the zoosporic true fungi.
Blastocladiomycota contains 2 Orders, 5 families and approximately 12 genera.
