Amanita punctata

Amanita punctata

Amanita punctata is a grey fungus found in most states of Australia.
Alien egg (Amanita punctata) Fungi season starts with some rain then an alien looking grey egg bursting from the earth. This is obviously some type of Amanita spp. (volva clearly visible) but so many are undescribed in Australia. 
After some discussion with fungi experts I believe it is Amanita punctata.

Appearance

Amanita punctata is up to 87 mm wide, at first globose, then convex, sometimes gibbous, then planar to slightly depressed, smooth, slightly sticky when moist, nonappendiculate, with a markedly striate to sulcate and rather short margin. The cap is very dark gray to grayish brown to smoke gray, and is darkest over the disc. The volva is present as occasional patches (especially in young material), with most of them near the margin.
