Two new species of this genus tuber It was discovered with the help of trained truffle hunting dogs.
“tuber “It is a genus of ectomycorrhizal fungi that produces paragenic fruiting bodies known as truffles,” said lead author Dr. Gregory Bonito of Michigan State University and colleagues.
“Many tuber The seeds are well known for their unique aroma and wide range of culinary uses. ”
“Like many other truffle-forming fungi, tuber The species lost the ability to forcefully release spores into the air and instead relied primarily on fungivores to ingest and distribute the spores. ”
“Mycivores such as porcupines, squirrels, pigs, and humans… tuber Sensitive to volatile compounds produced by truffles. ”
One of two new species, Tuber crable veratumis named after the truffle dog and Monza, the dog who discovered it with trainer Lois Martin.
The other is tuber cumberlandensis named after the Cumberland Plateau where it was discovered by Margaret Townsend and her truffle dog, Luca.

“There is a long history of using specially trained dogs, and less frequently pigs, to track the scent of truffles. tuber “In the wild,” the researchers said.
“Truffle hunting dogs are also regularly used for commercial truffle harvesting, as they can find consistently mature truffles faster than other methods such as raking.”
“Raking the soil to find and harvest truffles can have a devastating effect on both the roots and ascus of the plant host.”
“It could also lead to the harvesting of immature truffles.”
“However, a well-trained truffle hunting dog will always find mature truffles, reducing harvest effort and maximizing harvest quality.”
“As such, the use of truffle dogs to harvest commercial truffles has become the standard method used by truffle growers around the world.”
meanwhile Tuber crable veratum It is only known in eastern Tennessee, USA. tuber cumberlandens It has been opportunistically harvested for commercial sale from orchards in eastern North America.
“Historically, attention has been focused on the cultivation and sale of European truffle species, but there is increasing interest in the cultivation, wild harvesting and sale of North American truffle species,” Dr. Bonito added. .
“More and more people are trying their hand at growing truffles, which means more truffle dogs are needed to sniff out these fungal fruits because they grow underground.”
“If you have $20,000 worth of truffles growing underground, you have to find them before they rot. That's why dogs are so important.”
This finding is reported in the following article: paper in diary mycosis.
