Lentinus squarrosulus and Psathyrella atroumbonata, two edible indigenous mushroom species, were cultured in various different media supplemented with coconut, cotton, groundnut, butterfat, palm kernel and palm oil respectively, at 5 different rates. The interaction of the various oil types with different rates produced highly significant differences (p<0.01) in the mean mycelial wet and dry weights. The heaviest mean wet and dry mycelial weight of L. squarrosulus was induced by butterfat x 0.007 ml/ml while for P. atroumbonata it was cotton and coconut x 0.003 ml/ml, respectively.
