LESLIE, Michigan (WILX) -- When Ed Delaney told his wife he found a surprise for her. She thought she was getting flowers, but when she came downstairs Ed was holding this.
"I walked in and his arms were literally filled with this huge, disgusting white mass," said Amy Delaney. "I had this mushroom the size of two basketballs, and it kind of shocked her," said Ed Delaney.
A few days later, Amy found an even larger mushroom in their yard in Leslie. And then, two more of the giant masses popped up. We talked with an expert at Michigan State University to find out what it might be.
"Well, they're pretty clearly giant puffballs, Calvatia Gigantea, an appropriate Latin name for this monstrosities. And they are, to the best of my knowledge, the biggest mushrooms in the world," Jonathan Walton, Professor of Plant Biology, MSU.
But when Amy searched the web for pictures of giant puffball mushrooms this big, and had no luck. "I hadn't ever heard of anybody finding one this big," said Amy, And it's very possible no one ever has.
