For the second trial in the Isle of Armor, Mustard will task you with mushroom picking. Specifically, you will need to find 3 Max Mushrooms, which are red with a spiral pattern. Mustard gives you a hint that these mushrooms grow in dark, humid places! He’ll then tell you to search the area past the Forest of Focus called the Warm-Up Tunnel.
The mushrooms can be found at the end of the Warm-Up Tunnel. Just before picking them, your opponent will show up and challenge you to a battle.

After the battle retrieve the cluster of Max Mushrooms, then head back to the dojo. As a reward, you’ll get to keep the mushrooms. If you speak with the guy standing next to the stove, he can make Max Soup if you give him Max Mushrooms, which will enable certain Pokemon to Gigantamax (like your starter for example). There is a book located on the shelf to the right of the stove that contains a list of all the eligible Pokemon.
