 There are 11 accepted genera in the Macrotermitinae and about 330 species, with the greatest diversity being in Africa.About 40 species of "Termitomyces" have been identified as symbionts.In contrast to the fungus-growing ants in the tribe "Attini", the "Termitomyces" often bear fruiting bodies which produce spores, and it is believed that transmission of the fungus to other termites is mainly by horizontal transmission (sibling to sibling) rather than by vertical transmission (mother to daughter).
