The traditional Saint-Alvère market in the Perigord region (now known as Dordogne) opened on Monday, but closed its doors after just 10 minutes.
The traditional seasonal market, which runs until February, is famous for its black diamond truffles, a delight for foodies around the world.
But this year only 13 kilos were sold in total, seven kilos fewer than last year.
The reason for the lack of the Tuber melanosporum – dubbed “the black diamond” on account of its colour and extraordinary price – was put down to a lack of rainfall earlier in the year.
Reports suggest the truffle heartland went some 14 weeks without rain earlier this year.
“Fourteen weeks without rain is crazy. It’s the first year we have seen that,” Patrick Maxime who runs the market told Le Figaro newspaper.
How to spot a good truffle? “A good truffle has a perfume, an aroma. If it smells of nothing, move on,” said one specialist. The finest black truffles have a subtle aroma and an earthy flavour reminiscent of rich chocolate.
The shortage of black diamonds has of course impacted on the price, with Le Figaro reporting that category one truffles had hit €650 a kilo at the Saint-Alvère market.
Category two truffles were going for a slightly cheaper price of €400 a kilo.
“A lot of truffles are immature or damaged,” said Maxime.
Trufflers now face a barren season but are hoping a cold dry snap may improve their harvest over the coming weeks.
But their industry faces an uncertain future.
Scientists behind a 2012 study found that climate change was hitting the Périgord black truffle hard.
A century ago, French trufflers notched up a harvest that, according to legend, reached 1,000 tonnes in a year.
In the 1960s, truffle yields were still 200-300 tonnes annually.
But in recent years, they have been a meager 25 tonnes or so, prompting retail prices to rocket to as high as €2,000 ($2,500) a kilogram.
The Aquitaine region, or more to the point the departments of Dordogne, Gironde and Lot et Garonne, account for most of France’s truffle production.
In a letter to the journal Nature Climate Change, Swiss scientists said they now had clear data that drier summers were to blame, as this affected the oak and hazelnut trees on which the prized fungi grows, a process known as symbiosis.
