Many warts is a poisonous mushroom in the fungus family (Amanitaceae) native to New Jersey south to Florida and west to Texas plus Mexico and South America. It is found in pine-oak forests usually growing alone or scattered in summer and fall.
They grow up to 8 inches tall and prefer shady woodland areas. They have a strong chlorine odor and form a symbiotic relationship with the roots of trees for nutrients.
The cap is large, up to 8 inches in diameter, and is white covered with white, cottony scales. The gills are white, moderately close, and free from the stalk. The stalk is thick and greatly enlarged at base. The annulus (ring) is white, large, fragile, breaking away from the cap in large patches or adhering to the edge of the cap in large sections, and covered with scales on the underside. The spore print is white. It is considered to be very poisonous.
