My home is in Dazhou, Sichuan, and those mushrooms! Someone collected it before, and I don't know what it's called. We call it milky yellow because it secretes white juice! There is also a yellow, thick one with many small holes on the back. Let's call it a bubble! There is also a small one called Tricholoma matsutake, which grows in September, and some are called September fragrance!

That's all I know, I hope I can help you!
