Star mushrooms are inedible mushrooms distinguished by their unique star-shaped form and are a fascinating example of how fungi use clever ways to disperse their spores.

Where does it live?

Grows on the forest floor among fallen leaves, pine needles and decaying wood.

Where the spores form

Spore mass. Spores develop inside a special spore-bearing mass called the gleba. As the fruit body ripens the mass is laid open and the spores are released.

Did you know?

When it matures, the outer layer splits open into pointed rays, making the mushroom look like a tiny star. Raindrops striking the centre help puff its spores into the air.
