Where to sell mushrooms and other treasures in Legends: Z-A?

Question

Did they bring back the fanatics yet? It says the mushrooms are popular with a class of collectors

Comments

Similarly to how you will do this in newer titles, you will sell them, nuggets, pearls, and pretty feathers, at PokéCenters.

Probably a quality of life thingy

Answer 1

You can sell valuables at Pokecenters.

They fired the PokeMart guy, and now the Nurse Joys do all the things he used to do.

Unfortunately, they didn't bring fanatics back :(
