Trametes versicolor, aka the turkey tail, has been used in Asain medicine for centuries. It is proven to be a powerful booster for your immune system, improve digestive health, fight off infections, and it's recently been shown to contain very powerful anti-cancer properties. To be honest I forgot to peek at the underside to make sure it wasn't a false turkey tail, but I'm fairly confident that it's a versicolor based on the way it was growing. These fungi can be dried and boiled down to a tea. Many people keep this tea frozen until they feel a cold or flu coming on, and I've read an overwhelming amount of information validating it's benefits.
