EDIBLE when pure white inside: CRITICAL - ALWAYS cut specimen completely in half from top to bottom before consuming. Edible ONLY if interior is completely pure white and firm throughout. If any yellow, brown, purple, or developing structures visible inside, DO NOT EAT. This prevents consuming toxic lookalikes and immature deadly Amanitas. The distinctive scaled surface helps identification, but internal white color is the definitive edibility test. Cook thoroughly.
Large round to oval puffballs 4-12 inches diameter with distinctive thick, polygonal plates or scales on white to tan surface, giving areolate (cracked tile) appearance. Interior pure white when edible, turning olive-yellow then brown. Has small basal attachment but no distinct sterile base. Unique scaled surface pattern.
