Notes: Large Amanita species growing in large group underneath pine and oak trees. Sack like volva at the base of the stipe, powdery stipe with white fibrils near the apex. Universal veil remnants on the pileus you can see this in the pictures, margin striated. No ring.

Ambient temperature and humidity probably did slow the process or somehow added to the browning result.
I dried them with a powerful fan in a room with an average temperature of 78, its a room I use for all my cacti seedlings my company sells so it is also fairly humid.
For quite a while, Bas used the darkened gills of dried species of sect. Amidella as part of his key to the sections of Amanita. However, I discovered (from looking at dried material collected by Singer when he was at Harvard) that there were dried specimens with very pallid gills…barely changed from the fresh color. Experimentation revealed that if a forced air and a higher temperature are used in the drying process, the gills dry quickly and don’t turn color. So the color of dried gills is an artifact of the drying process.
I agree with Rods identification, added another pic that shows the chocolate colored gills.
They were perfect, looked like an egg with its top cut off. No data on spores, I do not have a scope. The volva was large, 2.5-3 inches tall and very wide.
It’s a shame you didn’t post a picture of the volval sac. Was it large and floppy or smaller and globose to thimble shaped or was it more shaped like a test tube? Any data on spores size/shape?
Would this be Amanita section Caesareae or Vaginatae?
These remind me of Amanita jacksonii, just not yellow/orange/red.
