Arthrobotrys oligospora (syn. Didymozoophaga oligospora) is a predacious fungus from the family Orbiliaceae. An adaptable fungus, strains have been found in a diverse range of soils where they can act as saprophytes, fungal pathogens and colonise plant roots to obtain nutrients. In the presence of nematodes they can also form complex three-dimensional network traps making them a biocontrol candidate for parasitic plant and animal nematodes, and in 2011 it was the first nematode-trapping fungi to have its genome sequenced.

The sequenced genome of A. oligospora is 40 Mb and contains 11,479 predicted genes. Comparative analyses revealed that it shares more genes with pathogenic fungi than non-pathogenic fungi. A combination of genomic, proteomic and qPCR data led to a hypothesis of trap formation involving the activation of multiple signal transduction pathways by the presence of the nematodes which regulate downstream genes involved in energy metabolism, biosynthesis of the cell wall and adhesive proteins, cell division, glycerol accumulation and peroxisome biogenesis.
