Huge white Italian truffle to be auctioned in New York

An Italian white truffle, reportedly the largest in the world, will be sold at an in-house and online auction in New York on Saturday.

Found last week in the Umbrian region of Italy and weighing 4.16lbs, it is nearly twice the size of a truffle that was sold in 2010 for $417,200 (£267,000).

Sotheby's said bidding is expected to start at $50,000 (£30,000) and could go much higher,
