Costa searches for truffles with his dog in the woods in Monchiero near Alba northwestern Italy
Truffle hunter Ezio Costa, 66, search for truffles with his dog Jolly in a wood in Monchiero near Alba northwestern Italy November 9, 2013. Costa's family have been truffle hunters for four generations. Located in the heart of the Langhe - the hilly southern area of Italy's northwestern Piedmont region - Alba is the country's capital of white truffles, a variety of the prized fungus which grows underground. Truffles are found two to eight inches (5-20cm) below the ground near the roots of trees. They give off an odour which lasts for a limited period of time and can be detected with the assistance of well-trained dogs and experienced hunters. Output of white truffles, which are not cultivated and only grow naturally in forests, has fallen in Italy over the past few years, largely because climate change has brought a damaging mix of drought and torrential rains.
