What you are asking is how to tell the difference between Hericium erinaceus and Hericium erinaceus. At first glance, the disc with good cortex, good maturity and high density looks good at the later stage, and then the pile type. Of course, most people's aesthetics are short piles, the flat-bottomed round is the best, and then the texture is clear and profound. Disks with extremely shallow textures will naturally wear out after playing for a long time, and some textures will be smoothed out. What will it be like? There are lines at both ends of the cone, and the most full belly in the middle has been polished.
