Orchid mycorrhiza define the fitness and diversity of the orchid family. Orchid mycorrhizal associations involve a plethora of distinctive nutrient transport systems, structures and phenomenon which have only been observed in the orchidaceae family. These interactions are formed between basidiomycete fungi and all orchidaceae species. The basidiomycete fungi most commonly found associated with orchids, rhizoctonia, are known for their saprophytic abilities making this fungi orchid association anomalous, allowing both the plant and fungi to access a source of carbon within the mycorrhizal association not available in arbuscular mycorrhiza. The way and degree to which different orchid species exploit these interactions varies.. Orchid
