Among 5 species ofTermitomyces spp. associated withOdontotermes spp.,Termitomyces microcarpus was the most dominant on the mound surface ofOdontotermes redemanni during the rainy season. This species was found to grow on the fungal comb fragments brought out by termites as the substrate for its growth. As a result, decrease in cellulose (5·9%), lignin (3·5%) nitrogen (0·54%), carbon (11·2%), C:N ratio (1·37), crude fat (0·48%), moisture (17·02%) and increase in ash content (20·15%) were observed. It was also observed thatTermitomyces microcarpus was rich in protein (39·16–43·37%) and mineral content.
