I thought I had photographed this fungi before, but it was growing on a dead stump. This fungi was growing in sandy loam in an open grassy ara shaded by some Eucalypts. The cap was about 60mm across and the stem about 100mm. The ring\veil, I thought was a bit unusual as it felt a bit like plastic, and was attached to the volva area. At first I thought it had dropped down, but I was unable to move it up the stipe. Also the root system (an orange colour) was evident when the specimen was cut to be seen a short distance up the inside of the stipe.The gills were close and fine. There was one more specimen close by.

When I removed this fungi from its habitat, as you know I looked at the base and was a bit surprised at the colour and the makeup in that coloured area in the centreof the stipe. I didn’t mention it in my notes,but, the idea that ran past my mind was that it could have been the remnants of a root that the fungi had attached itself to. I agree with Rod about the volva\bulb. To my inexpert eye I did not detect a bulb or swelling at the base. kk
This is either a species of sect. Vaginatae or sect. Amanita. In Oz BOTH could have graying volval limbs. I am probably going to suffer embarrassment at the hands of one of these critters (not the one depicted) because of remote mycologist ignorance syndrome. When a group of us described A. murinoflammeum from Australia, I thought it belonged in what is now called sect Caesareae; however, to me it looks more and more like A. umbrinella, which is a species of sect. Amanita. Knowing whether a bulb was present in the button stage is very important for identification of species of sect. Amanita that look like a species of Vaginatae or Caesareae after they are fully expanded. The orange pigment is probably cause by insects tunneling in the flesh. A pristine specimen of this species might very well be white through and through. When you look at picture numero uno at top magnification you can see the marks of the gill edges on the little raised limb (the volva’s internal limb or limbus internus) which used to reside between the developing stipe and the developing gill edges. In the same photo, you can also see the marks of the cap striations on the inside of the graying volval sac (it’s not an annulus). If the based of the stem is hidden becase the volval sac is bent downward (which I believe it is), I can’t be sure if there was a bulb at the stipe base or not. After a long look, I think maybe there wasn’t a bulb.
You sure do come up with some real gems, Ian.
If we could get a consensus on the sect., we might be able to come up with a species name…although my impression is that Oz is in the same boat as the rest of the world and many (or most) of the species of sect. Vaginatae are not named yet.
without a partial veil or ring. you are seeing the universal veil remnants at the base.
beautiful specimen, reminds me a bit of our protecta with that darkly ornamented stipe and striate margin, but this is something unique to OZ I’m sure. Orange color at base looks like staining/insect tunnels, and sometimes even mycorrhizal mushrooms can grow up and out of well-rotted wood, so you may well be seeing this for the second time. Would’ve liked to have seen a complete base/volva to this one.
