Eyes3
Recognized by sight: Leucoagaricus barssii is known from Australia. The other possibility is La. leucothites, but the greyish pileus, the shape of the annulus and the deep rooting fit La. barssii better.

Thanks Debbie,
I should remember this one as we have a retired footballer down here with a similar name and he was a bit rough around the edges too.

if you enlarge the cap photos…

you can see the shaggy edge to the cap typical of barssii but not leucothites, among the other differences mentioned by Else.
search this site for many other photos of barssii to compare.

Stinky fishy mess

I went back to the site and evidence was significantly decomposed, cap tops not as deteriorated as gills and stalks. Warm moist soil under a thick matt of Kikuyu grass grown as a cut lawn on a median strip. A large Agonis flexuosa (Willow Myrtle) is in the front yard. Not sure why the other photos failed to upload. Will try to include a site photo also. Hope this helps.

That looks right comparing with other obs. But I would like to see a close up of the cap top.

Species is known only from NE North America.

Oz taxa are so often quite distant from North American taxa, that I think the ID is unlikely. If it is isolated in a grassy area with no nearby trees, there is a chance it is not an Amanita. There is only one grassland Amanita presently known from Australia; it has been determined by several people as A. nauseosa. I’m not sure of that ID, but I’ve never seen any Australian material that was determined under that name. However, if the name was correctly applied, a brownish species would not be a match to it.

It would be good to hear what other folks think this entity might be.
