A Dried Shroom is an item in the Paper Mario series. The mushroom heals one HP. Dried Shrooms are sold at Westside Goods in Rogueport for two Coins. Any mushroom becomes a Dried Shroom when cooked with a Mr. Softener.
Since Dried Shrooms are so pathetic, Mario should either sell it or cook it with another item. Mario has to buy a Dried Shroom and a Dizzy Dial to gain access to Don Pianta.
