Gold rush for Nepal's 'Himalayan "Yarsagumba"
Yarsagumba with its Latin name cordyceps sinesis literally means summer plant and winter insect in Tibetan. Before the rainy season begins, spores of the cordyceps mushroom settle on the heads of caterpillars’ that lives underground. The fungus gets so much into the body of the caterpillars’ that it grows out through its head and drains all the energy from the insect and ultimately it dies. Yarsagumba is a unique caterpillar-fungus fusion that occurs when parasitic mushroom spores (Ophiocordyceps sinensis) infect and mummify a ghost moth larva living in the soil. A spindly fungus later sprouts from the dead caterpillar host’s head. Two to six centimeters long, the fungus shoots above the soil, acting as a tiny, finger-shaped flag for harvesters to find. This peculiar hybrid is the world’s most expensive biological resource.
