Possibly Pleurotus nidiformis. One of the best-known bioluminescent fungi in Australia. This is a  large, irregular-shaped fungus with little or no stem, which often grows in dense clusters at the base of living or dead eucalypts.  Bioluminescent mushroom light is created by a chemical reaction. A substance called luciferin reacts with an enzyme, luciferase, causing the luciferin to oxidise, with the consequent emission of light. Fireflies, glow-worms and a number of marine organisms, such as fish, use bioluminescence to attract prey or mates. | Tablelands | Australia
