Deadly poisonous. "Amanita bisporigera is by far the most toxic mushroom known in North America." (M. Woehrel & W. Light. Mushrooms of the Georgia Piedmont and Southern Appalachians, 301.)
Usually found solitary, occasionally in small groups. On ground in hardwood or mixed forests, also on lawns.
Amanita virosa and Amanita verna often appear in older field guides. Recent research indicates that neither of those species may exist in North America.
Cap: Conic to flat, white (may have discolored disc), smooth, dry to sticky, unlined margin, white flesh. Disagreeable odor in age. Gills: White, close, free. Stalk: White, typically tapers up, skirt-like ring near top, smooth to floccose, hollow, sac-like volva. (J. Solem, pers. comm.)
