1 First of all, look at the color. The surface of the real Cordyceps sinensis "worm body" is dark yellow to light yellow brown, and the color of most worms will change to some extent at the junction of the worm body and the grass. The "grass" part shows the color of dead branches, which is darker.
2. Second, look at the appearance. There are 8 pairs on the ventral surface of Cordyceps sinensis, and 4 pairs in the middle of the worm are very obvious.
3. Third, look at the cross section. Cordyceps sinensis has obvious lines after opening. Cordyceps sinensis has a black core similar to a "V" shape in the middle, and some may be black spots. This black core is actually the digestive line of worms.
4, finally smell the smell, the real Cordyceps sinensis has a slightly fishy smell of dry rot insects and a mixed aroma of straw mushrooms.
