Tim Terry claims he found Australia's first black truffle in the soft soil of his farm in central Tasmania 20 years ago.And after two-plus decades of searching for and harvesting the coveted fruiting fungi, some finds still surprise even him.Last week, he got one of those surprises, when a truffle-sniffing dog named Poppy discovered the farm's biggest-ever find.The black truffle would've been worth around AU$1,500 (US$1,000), but they didn't sell it.Due to restaurant closures, the farm decided it would have to ignore that potential profit.He cut it up and said it will probably end up being eaten by he and his family
