Physiologically
and morphologically, as obligately osmotrophic heterotrophs, the Peronosporomycetes are ‘fungi.’ They are
phylogenetically separate from the Mycota (an alternative taxonomic name for
the kingdom Fungi) and sometimes are described as Oomycota. The biflagellate, anisokont
but nonstraminipilous Plasmodiophorales
and the uniflagellate Chytridiomycetes
likewise are unrelated. The Chytridiomycetes
may be an early offshoot from the phylogenetic line leading tothe nonflagellate
Mycota.
The
Peronosporomycetes are algae fungi or
cellulose fungi, form a class within the Stramenopilen,
and therefore are much closer to brown algae, golden algae, and diatoms used as
the genuine fungi. The taxa include several plant pathogens, such as the
causative agent of late blight of potato and downy mildews.
The
Peronosporomycetes include the most
numerous, most important, and earliest known (with mid-eighteenth century reports
for Saprolegnia on fish) water molds…
