Pseudofungi

Pseudofungi is a grouping of heterokonts, also known as the Heterokontimycotina. It consists of the Oomycetes and Hyphochytriomycetes. Although numerous biochemical, ultrastructural, and genetic traits clearly place them in the heterokonts, their growth form (featuring hyphae) and mode of nutrition (osmotrophy) resemble those of fungi (which are not closely related).

Hyphochytriomycetes are eukaryotic organisms in the group of Stramenopiles (Heterokonta).
