This species is deadly poisonous--one of the most toxic of all North American mushrooms.
This species was introduced from Europe both to central California (late 1930s) and the Mid-Atlantic (1960s and 1970s) and continues to spread (J. Solem, pers. comm.).
Cap: Usually a mix of olive and gray-brown tones with a pale, non-striate margin, smooth, dry, convex to flat. Gills: White, crowded with white partial veil. Stalk: White, tapers up, membranous white pendant ring persists, bulbous base with fragile, sac-like volva. (J. Solem, pers. comm.).
Single or scattered on ground mainly under oaks, but sometimes under planted conifers or in grassy areas near trees. [Published accounts list everything from "various oaks in the East" (M. Kuo); "mixed woods" (Bessette, Bessette, & Fisher); "oak, but also under imported species of pine and even Canadian hemlock and other species of native conifers" (Baroni); and "under conifers and hardwoods"(Lincoff) (J. Solem, pers. comm.).
