Fascinating fungus

Walking in the Murramarang National Park, I was fascinated by these fungi (up to about 15cm across - see second image in PiP). After spending some time working to identify them, I'm fairly sure they are Ghost Fungus (Omphalotus nidiformis) which glows in the dark (see this link). Unfortunately they're a bit far for a night walk, so I must look for some closer examples to get a shot of them glowing.
