The most well-known and studied is Cordyceps sinensis. In 2007, scientists discovered that this species is unrelated to most of the others and they placed it in an entirely new genus (Ophiocordyceps). Although its name has changed (now it is known as Ophiocordyceps sinensis), it is still commonly referred to as C. sinensis, or just cordyceps.
Cordyceps is no typical mushroom. The way it grows in nature has fascinated scientists for a long time and earned it the nickname "caterpillar fungus".
Namely, the spores of the fungus infect moth caterpillars. These tiny spores then grow into a large fungal mass called mycelium that spreads throughout the insect body, eventually killing the larvae. Victoriously, a thin stalk called a fruiting body then sprouts from the corpse, releases spores, and continues the cycle.
