Then I would suggest that the species may be Amanita volvata.

Very best,


The volval limb is not the same height all the way around

I’ve added some more pictures I took this morning to show the “other side” of the volva on the 2 specimens
I also added spore measurements and a photo of the spores

As always, Rod, thanks for your response and sharing your Amanita expertise

The smaller fruiting body seems to have a volva with more even distribution of the volval limb. From the proportion of height of stem and breadth of cap, the intensely floccose upper stem, and the size of the volval limb in the smaller f.b., I’d say this might be A. volvata, rather than whetstoneae.

Very best,
