 The fungi concerned are species of "Termitomyces"; it is unclear whether one species of termite is always associated with one species of fungus, and it is probable that several species of termite may utilise a single fungal species.The worker termites bring plant material such as dried grass, decaying wood and leaf litter, back to the mound.This material is chewed up and semi-digested by the termites, fertilised with their faeces and placed in the chambers where it is quickly colonised by the fungus to form a "fungus comb".
