Ganoderma lucidum and Ganoderma lucidum are recognized in Pharmacopoeia. Other Phellinus linteus, wooden hoof, etc. It's not really ganoderma lucidum.

If it is an identification variety, you can judge it by sending high-definition photos here.

If it is wild Ganoderma lucidum, it can be judged according to the way of obtaining it (whether it is picked in the wild or planted by itself). If it is purchased, it is difficult to judge whether it is really wild Ganoderma lucidum only from the appearance of the purchased Ganoderma lucidum.

There are still many professors in the Academy of Agricultural Sciences who have never seen the real wild Ganoderma lucidum.

Jilin Ginseng Research Institute can issue a certificate of wild Ganoderma lucidum. At least they've done it before. Probably the certificate of 40 yuan, the number can also be checked online. Similar to the appraisal certificate of jewelry store, but their appraisal contents are all false. They can identify ginseng just dug out of cultivated land as wild ginseng and cultivated ganoderma lucidum as wild ganoderma lucidum. If you give money, they will give you any result you want. Almost all those who used to sell wild ginseng in Changbai Mountain had their fake identification certificates. At present, the identification of precious Chinese herbal medicines, cultural relics and jewelry in China is similar.
