Eleven white truffles have gone under the hammer in Italy for 274,200 euros ($367,620), including a pair bought by an anonymous buyer in China who paid out 90,000 euros, auctioneers said Monday.

A “famous Chinese writer” bidding by satellite telephone from Hong Kong fiercely outbid competitors for a 950-gram pair of truffles, organisers said, paying three times the price of gold for the white delicacy.

The auction, which took place Sunday in the Grinzane Cavour castle in the Piedmont region of northern Italy, also saw an unnamed buyer snap up a 305-gram specimen to be given as a gift to New York’s new mayor, Italo-American Bill De Blasio.

The sums raised at the 14th edition of the White Truffle of Alba auction will be given to the Piedmont Foundation for Cancer Research. The funds raised by the Hong Kong sale will go to the Mother’s Choice institute which cares for orphans and mothers in difficulty, the organisers said.
