There is ongoing debate as to exactly how to classify Prototaxites as the evidence suggests that it may be either a true fungus or a symbiotic lichen. This is quite important when we consider this question because fungi are far more sensitive to their growth environment than lichens. A giant lichen similar to Prototaxites probably could survive in the rather hot, dry environment of Australia or Madagascar with minimal competition and few creature to eat it. Lichens are hardy enough that they manage to survive in the McMurdo Dry Valleys Australia is paradisaical by comparison. A giant true fungus would be restricted to wetter areas like forests and swamps where they can be sheltered from heat and direct sunlight and have access to large volumes of the organic matter they depend on for sustenance.
