Giorgio’s white mushrooms are nutritious with riboflavin, ergothienine, low fat, low sodium. White mushrooms are the best selling variety of mushrooms in the US. They vary in color from white to off white or tan color. We package white mushrooms in bulk cases from 3 lbs to 10 lbs, and in sizes ranging from Small or button (0.75-1.25” diameter) to jumbo (2.75-3.5” in diameter). Another name for white mushrooms is the “button mushroom”. That can be confusing since button mushroom is sometimes also used to describe a size as noted above.
