Pseudofungi: Information from Answers.com

Pseudofungi is a Heterokont grouping,^[1]^[2] also known as the Heterokontimycotina.^[3] It consists of the Oomycota and Hyphochytridiomycetes.^[3] Although numerous biochemical, ultrastructural, and genetic traits clearly place them in the heterokonts, their growth form (featuring Hyphae) and mode of nutrition resembles the fungi (which are not closely related).^[3]
