The mean fresh weight of the fruitbodies produced on paddy straw, oil palm fibre and a mixture of oil palm fibre and sawdust were high with 16.3g, 16.3g and 15.3g respectively. Also the mean fresh weight of the fruitbodies produced on sawdust was relatively low. The mean diameter of the pileus of the fruitbodies as well as the mean dry weight of the fruitbodies produced on the different substrates also appeared in the order of the earlier parameter mentioned. While the fruitbodies produced on paddy straw had the same mean diameter with those produced on palm fibre (3.7cm) the mixture of oil palm fibre and sawdust produced pileus with a mean diameter of 2.9 cm. Sawdust, however produced the smallest sized fruitbodies with a mean pileus diameter of 1.8 cm.
