Nematophagous fungi: a new Myzocytium

Abstract

Myzocytium humicola is described as a new nematophagous fungus endoparasitic on Rhabditis. This species possesses unequally biflagellate zoospores. These do not attack the nematodes directly but encyst and produce adhesive buds that attach to the cuticle of passing nematodes. The oogonium is fertilized by the passage of the antheridial protoplasm through a pore in the contiguous wall. The resultant oospore has a thick, smooth or finely roughened wall.
