Let me give you some common sense first: Fritillaria can be divided into three types: mussels, mussels and furnace mussels. Now they are all mixed, and the more mussels (very small), the more expensive they are.
The picture you sent is very clear. To tell the truth, both of them are adulterated, and Fritillaria and Fritillaria thunbergii are adulterated. The more adulteration, the cheaper it is.
