Golden Mushroom (crownless)

Golden Mushrooms, also known as Gold Mushrooms, are an extremely rare type of Mushroom. They resemble a crownless, dark-stalked version of the Golden Dash Mushroom from the Mario Kart series or a Gold Mushroom from New Super Mario Bros. 2 with the light and dark areas switched.

Mario Party 2
In Mario Party 2, Gold Mushrooms appear in the minigames Grab Bag and Rakin' 'em In, where they are worth three Mushrooms. Other Golden Mushrooms appear as a usable item, though these are actually a nonstandard design of Super Mushroom.

Mario & Luigi: Superstar Saga / Mario & Luigi: Superstar Saga + Bowser's Minions
In Mario & Luigi: Superstar Saga and its remake, it fully restores both Heart Points and Bros. Points for a single brother. There are only five Golden Mushrooms in-game, though it can also be stolen using Swing Bros. from Fawful and Popple (in the original game). In the remake, bosses like Iggy, Morton, Wendy, and Larry always drop a Golden Mushroom when defeated. Ten Golden Mushrooms can be obtained from the Information Booth after 800 attacks are dodged. They also have a chance to be dropped by Clumphs and Boos.

In Mario & Luigi: Bowser's Inside Story and its remake, the Star Candy replaces the Golden Mushroom, with the Cheesy Drumstick being the Bowser equivalent in the remake. In Mario & Luigi: Dream Team and Mario & Luigi: Paper Jam, they are replaced by various Candies.

Super Nintendo World
A Golden Mushroom is a key item in the "Power-Up Band Key Challenges" attraction at Super Nintendo World in Universal Studios Japan, where it is stolen by Bowser Jr. and attendees help Peach recover it by collecting three keys and defeating Bowser Jr. in an interactive boss battle.
