Although poisonous, and closely related to the introduced species Amanita muscaria, this pretty, indigenous fungus emerges from the floor of Eucalypt forests like a sphere of yellow gelati while still covered in the juvenile down so characteristic of the family – This species has an ectomycorrhizal relationship with Eucalyptus. It occurs in south-west Western Australia, and in the forests of South Australia and around up into southern Queensland.

There is some radial grooving on the cap and that and its tendency to smaller size helps distinguish it from the introduced species Amanita muscaria  . It is quite common and may occur singly or in groups, although I have only seen it singly.
