I need help on getting the mushroom for the 1st summoning test. Orginally I had picked up the mushroom to finish the quest, but I decided to reload a prior game from earlier since I destroyed two of the chests behind the 'door riddle with the 4 colored button'. Anyway, the mushroom in no longer in my inventory and it's no longer in the area where I orginally found it. Any ideas on how I can restore the dungeon to get the mushrom back?
