A GHOSTLY discovery in the rainforest of Mt Colliery has Warwick photographer Ken Laws scrambling through the bush at night, camera at the ready.

After twilight, Mr Laws set out in search of a special "ghost fungus” that lets off an eerie green glow you really have to see to believe.

Omphalotus nidiformis is the main type of fungus Mr Laws captures on camera in the Mt Colliery area.

By day these mushrooms look like your average plant, but by night they let of an incredible, luminous glow.

A chance sighting in a nearby rainforest led Mr Laws to start photographing the magical plants.

"My bother and I had heard about these mushroom and we went out one night to see if we could spot them.”

Their search in the dark returned no results, until they were driving out of the rainforest and decided to flick their headlights off for a second.

What they saw in front of them was a whole tree full of glowing mushrooms.

It was pretty impressive,” Mr Laws said.

"These were almost the size of a dinner plate and a whole tree of them, all lit up.”

Mr Laws said the mushrooms change in radiance throughout their life cycle.

"When they first come out they don't glow at all but when they get a bit older and the spores come out they glow really brightly.”

The glowing properties of the fungus have been observed to attract insects like bush snails, bush cockroaches and beetles, which help spread the spores of the plant.

But finding the fungi is not your average walk in the park.

Mr Laws has been known to trek two hours in the bush at night to spot the plants.

"Yeah, it can be a bit of an adventure to find them.”
