In nature, fungi are ubiquitous, having evolved over time to occupy a wide range of ecological niches. To occupy these niches, they must be involved in primary resource capture which is determined by the ability to germinate and become established rapidly and to produce the necessary extracellular enzymes in the immediate environment. Their activity will be further impacted upon by prevailing abiotic factors such as temperature, water availability, gas balance and pH. It has been suggested that both primary and secondary resource capture are in a state of flux and determined predominantly by prevailing biotic and abiotic interactions (Magan and Aldred 2006). Thus, niche occupation is determined by a complex of interacting factors. Certain species may occupy similar general niches because of their ecologically similar behaviour within
