Of the 100,000+ known species of fungi only about 80 are bioluminescent (<0.1%) and there are only a handful of these in Australia. So I'm pretty chuffed to be surrounded by these beauties at my camp in Blue Knob (northern NSW).
Without access to a mycologist I'm guessing these are Mycena chlorophos. They grow amongst the litter of the forest floor, decomposing plant matter. They actually bioluminescence 24/7 and while they are pretty non-descript in daylight, at night they really stand out beautifully against the darkness.
