zz agaric (stem; gills white/cream)

A Macrolepiota or an Amanita or something else, the tendency for the gills to be developing a yellowish colouration and a slightly thick stocky stipe give me some pause for thought and hesitancy regards to putting a name on this. It appears to be occurring in grass among eucalypts, shame one can't see the base of the stipe and whether the gills are free or not. one for Heino.

There were no eucalypts near the fungi, only grass. The nearest trees were several metres away. What is the stipe? These are only up the street so I can see if I can get some better photos. I have other photos but had trouble getting photos of the underside in focus on my small camera. Will add one extra photo of a broken one.

Sorry my apologies, I looked at your profile and it said an interest in fungi and I assumed more knowledge then clearly exists. So here we go - the stipe is the stalk or stem of the mushroom. At the bottom of the stipe (often but not always below the ground level) some species in some genera (e.g. Amanita) have a structure called a volva (may be an extensive cup like sack or merely reduced to a few scales on a swollen base, or somewhere in between) this can be an important feature for identification. With a tall specimen like this to see how or if the lamellae (gills) attach to the top of the stipe you can use a small makeup mirror such as (https://www.ebay.com.au/itm/Small-Travel-Portable-Folding-Handbag-Pocket-Compact-Makeup-Mirror-Silver/233036370150?_trkparms=aid%3D555018%26algo%3DPL.SIM%26ao%3D1%26asc%3D20140106155344%26meid%3Da943521d0d034fa79c7f4c3bddc0451f%26pid%3D100005%26rk%3D9%26rkt%3D12%26sd%3D253703836742%26itm%3D233036370150&_trksid=p2047675.c100005.m1851). I mirror such as this resides in my camera bag. As far as the eucalypts go, where to start? If you look at a a large eucalypt (and exclude the trunk) you will see lots of branches and leaves, if you were able to look underground and could see the roots then you might see a similar amount of material associated with the roots as with the branches and leaves. At several metres from the tree your fungi would be well within the root zone which could easily extend tens of metres from the trunk depending on how large and old the trees are.

Thanks Ken. Yes I have a love of fungi, but not an extensive knowledge of them. I do a family newsletter titled Under the Toadstool but doesn't mean I know a lot about them, just that they fascinate me. Will look at the web site on how to use the makeup mirror. Currently I use my DSLR to photograph the top of fungi but have a small compact Nikon that I turn upside-down to try to photograph the underside.

I cannot improve on what Ken said about the identity of this fungus.
