Abstract Basidiomycota are, in most terrestrial habitats, the primary agents of organic matter decomposition. They play a key role in associated ecosystem processes. Inevitably they interact frequently with invertebrates, and these interactions are highly dynamic. They may be direct or indirect, and prove beneficial or detrimental to either or both partners. In this chapter the variety of interactions is explored and the impact of basidiomycetes as a food and habitat resource, and as a predator is assessed. The consequence of fungal-invertebrate interactions on fungal community structure and fau-nal behaviour is also considered, as are the implications of these effects on nutrient cycling and ecosystem processes such as decomposition and productivity. The sensitivity of the interacting organisms to changes in climate, and general environmental change, with consequential effects on ecosystem activity, is also discussed.
