“Since there is currently only one other disused railway tunnel used for mushroom growing in the whole of Australia, his mushrooms have evolved to fit an extremely specialised environmental niche: they are species designed for architecture.”
…
“The tunnel for which these mushrooms have been so carefully developed is 650 metres long and about 30 metres deep. Buried under solid rock and deprived of the New South Wales sunshine, the temperature holds at a steady 15º Celsius. The fluorescent lights flick on at 5:30 a.m. every day, switching off again exactly 12 hours later. The humidity level fluctuates seasonally, and would reach an unacceptable aridity in the winter if Dr. Arrold didn’t wet the floors and run a fogger during the coldest months”
