Description - what does it look like? 

Growth: The Grey Spotted Amanita is a mycorrhizal fungi growing in association with different trees. fruits are often found individually, but can also be found in small groups

Grey patchy fragments of the veil/volva remain on the cap, though these can be easily washed away or wiped off.
