Common name: Carrot Foot.  Uncommon in my
experience; found one year during a rainy
month of August, which doesn't happen often.
Amanita daucipes
The largest portion of this mushroom's basal bulb develops above ground.
Up to 10 inches tall, cap 5.5 inches wide. Big mushroom!

"WARNING: I have been told on a number of occasions that the
stipe's bulb is edible. Considering the poor knowledge of toxins in
section Lepidella and the established fact that kidney and/or liver
failure is associated with ingestion of species in section Lepidella, I
cannot recommend that this species be eaten. -- R. E. Tulloss"
