How to trace the geographic origin of mushrooms?

Mushrooms became one of the most popular food resources worldwide that are very appreciated by consumers. Fresh produce properties including mushrooms are obviously varied based on their geographical origins. In view of the significant increase in the world's production of mushrooms, this will be accompanied by the increasing attention of all actors in the international food trade system (producers, traders, consumers and the authorities) to obtain a safe and high-quality commodity. This can be achieved through the implementation of an efficient and universal geo-tracing technique. Current approaches of geo-tracing mushrooms are few and have several limitations. Our intent is to suggest the DNA barcoding as a potent and universal method for mushrooms geo-traceability.
