Irvingia gabonensis are seeds of a small mango-like fruit found in West Africa. The seeds when ground into paste are highly mucilaginous and are used in thickening soup while Colocynthis citrullus (Egusi) are seeds of a creeping annual and an intercropping plant made use of in traditional farming practices. When the seeds are coarsely ground up, the also assist in thickening soups. Fifteen samples each of Irvingia gabonensis (Ogbono) and Colocynthis citrullus (Egusi) seeds were randomly purchased from 5 retailers in each of the three (3) major markets in Ado-Ekiti Ekiti state, Nigeria. The seeds were cultured on potato dextrose agar in the laboratory and incubated at 25° C for 5- 7days. The fungi isolated from Irvingia gabonensis were Rhizopus nigricans, Mucor mucedo, Trichoderma viride and Aspergillus flavus. The most frequently occurring fungi was Mucor mucedo, then Trichoderma viride while Aspergillus flavus had the least frequency of occurrence. fungi isolated from Colocynthis citrullus were Aspergillus niger, Mucor mucedo, Rhizopus nigricans, Trichoderma viride and Penicillium italicum of these the most frequently occurring fungi was Rhizopus nigricans followed closely by Mucor mucedo. Trichoderma viride and Aspergillus niger had the least frequency of occurrence. It was concluded that the fungi associated with these seeds were of the group Micromycetes. The significance of these results was discussed.
