Every year at the end of the rainy season, the villagers in Nong Prue go in search of the termite mushrooms. These are then sold from stalls lining the road, to buyers who will drive from Bangkok for these rare and sought after delicacies.
They germinate in the organic matter left behind in termite nests after the ants swarm to establish new colonies. They can be found in Phetchaburi, Kanchanaburi and the more mountainous areas in Suphanburi. But the best, the sweetest mushrooms are found in Nong Prue where they can fetch prices in excess of B600 for a kg.
