Reishi Mushroom (Ganoderma lucidum) - Extra Large Set of 4

Thank you for looking. This appears to be what is called Saru no Koshikake (Reishi mushroom). I don't know much about it myself. It seems my acquaintance found it while hiking and digging for wild yams. Would anyone be interested in it? This is a low-priced set of 4, including two extra-large sizes, approximately 21.5 x 14.5 cm and 30 x 17 cm, plus two smaller ones. It is said that items of this size are likely over 10 years old, possibly even over 20 years old. It is apparently used in traditional Chinese medicine, and it takes many years for them to grow this large. They are large enough to be displayed. This is a rare, exceptionally large size that you don't see often! If you are interested, please act quickly. It is said to be brewed and drunk, but I have no knowledge of this and don't need it, so please take it if you can use it or want to display it. This is a natural item as shown in the images, with some minor scratches and dirt. Shipping will be approximately 60-80 size. It was mentioned that clean items of this size are rare, but I'm not sure. Shipping will be on weekends due to my schedule. Also, I am unable to answer any questions as I have no knowledge of this item. Thank you for your understanding in advance.
