Notes: Keyed it out using Mushrooms Demystified and photos/descrip from mykoweb.
Key sequence I used in MD started on page 266 1-15-22-23-24-26-31-32-33 = Rubescens but from mykoweb and here see it is novinupta
Pink/lilac tinged all over, cap convex/button when small 3-4cm, plane when large (up to 8cm). Flesh pink even inside but with white. Gills are pure white, closely spaced but even. Spore print is white. Stalk feels hollow but has a hard/white outer sheath and soft spongy red/pinky spongey or jelly like stuff up center though older one’s were hollowed out (jelly dried up?). Most I found the bottom of the stalk was larger than stalk and bulbous with a collar line but the sac is not separate from the flesh (stuck to it but can be scrapped off with a knife).
My aplogies for the poor photo quality, I hope to have a real camera soon.

Don’t expect that there is a sack on the base of every amanita. This is a false impression given by crude explanations in some field guides. Volvas have many textures and many different internal structures, which result in their breaking up in so many different forms of warts and powder and membranes, etc.
Volva = the outerlayer that develops as protection while the rest of the fruiting body develops.
Volva does not = bulb.
Most bulbs are tissue that remains in a somewhat “primitive” or “undeveloped” state while the stem takes on the the particular internal structure that is peculiar to only Amanita and Limacella…baseball bat shaped cells aligned vertically and acting as “inverted pile drivers” to expand the stem rapidly with hydrostatic pressure. Bulbs are said to exist in species in which the cap and stem develop in the upper part of the early “button” stage of development (primordium).
There is no bulb in the species of some sections in which the stem develops and expands totally from a central point in the primordium. These are the amanitas with totally elongating stems (sections Vaginatae, Caesareae, and a good chunk of sect. Amidella).
