SA is home to hundreds of species of fungi, but did you know some of them glow in the dark? Here’s where to look.
Ghost mushrooms, or Omphalotus nidiformis, get their name because they have an eerie glow. The mushrooms’ cup-shaped fruiting bodies grow on pine stumps and other rotting wood, and can grow as big as 20 centimetres across.
In daylight, they’re a creamy white colour, sometimes with brown, black or purple shading, but at night they really come into their own, glowing green.

Like glow worms, fire flies, and sea sparkle, ghost mushrooms produce light known as bioluminescence through an internal chemical reaction.
Where to find them
The best place to find ghost mushrooms in South Australia is in Glencoe Forest near Mount Gambier. Forestry SA opens Ghost Mushroom Lane to visitors during May and June every year, and entry is free.
The South East is the perfect climate for ghost mushrooms due to its higher rainfall. Read about a recent sighting in Padthaway Conservation Park.
After wet weather, you may be lucky enough to find these amazing fungi in other parts of SA as well, especially where there are pine trees.
They have been seen in the Adelaide Hills, especially in Para Wirra Conservation Park and Scott Creek Conservation Park, as well as Flinders Chase National Park on Kangaroo Island and even on Eyre Peninsula, so keep an eye out next time you’re on a walk.
Just remember, ghost mushrooms are for looking at, not eating. Like many wild fungi, they are poisonous, and while they aren’t likely to kill you, the effects include vomiting and stomach cramps and are deeply unpleasant.
