Hyphochytrids are

Stramenopiles
(Heterokonta).

Characteristics

They are distinguished by an anterior tinsel flagellum

zoospores
. Also they have a rhizoidal or hypha-like vegetative system (hence the prefix "Hypho-").

Classification

This group may be put alternatively at the phylum, class, subclass or order level, being referred to as Hyphochytriomycota, Hyphochytriomycetes (or Hyphochytrea), Hyphochytriomycetidae (or Hyphochytridae) and Hyphochytriales, respectively. The variants Hyphochytridiomycota and Hyphochytridiomycetes are also sometimes used, presumably by analogy to the Chytridiomycetes, or due to the perpetuation of a typographical error. However, the stem is Hyphochytri- (from Hyphochytrium) and not Hyphochytridi- (from Chytridium).[8]

In the past the classes Hyphochytridiomycetes,

Stramenopiles
.

Hyphochytriomycetes are closely related to

Oomycetes.[9]

Order

Hyphochytriales
Bessey 1950 ex Sparrow 1960

Diversity

This is a relatively small group, composed of about 16 known species, which may be due in part, to sampling methods of scientists.
