Fungi producing ornamented asexual structures and belonging to the Oomycetes (Trachysphaera) or Zygomycetes (Azygozygum, Mortierella) are described. They were studied by light and scanning electron microscopy while also mating experiments and carbohydrate analyses were performed. Azygozygum chlamydosporum is closely related to Mortierella indohii and therefore Azygozygum is considered to be a synonym of Mortierella. Mortierella echinosphaera spec. nov. is also closely related, but no zygotes are known, only ornamented chlamydospores have been observed. Absence of glucuronic acid and fucose and a low glucosamine content in Trachysphaera fructigena show that it belongs to the Oomycetes.
