From the Super Mario Wiki, the Mario encyclopedia
The Golden Mushroom (sometimes referred to as a Gold Mushroom) is an item that appears in several Mario games. It is a rare Mushroom, sometimes depicted having a gold crown with red jewels on its cap, and it always gives the player a positive effect when used. Golden Mushrooms sometimes vary by color and luster between games, but they are always a strong item.
Super Mario series
Super Mario World
Originally a flying Golden Mushroom would have appeared in that game but was removed for unknown reasons. They are worth extra lives, like 1-Up Mushrooms. The palette they use is actually the beige palette used by Monty Moles and Floating Mines.
New Super Mario Bros. 2
Gold Mushrooms appear in New Super Mario Bros. 2 in the Coin Rush mode and replace 1-Up Mushrooms, and upon contact, Mario gets 50 coins (or 100 coins if he is Gold Mario). It lacks the crown from its contemporary Mario Kart appearances and the coloring is reversed from all other occurrences, with the spots being darker than the background.
Mario Kart series
The Golden Mushroom appears in Mario Kart 64 and all main games starting from Mario Kart: Double Dash!! Since Mario Kart 64, it gives the player an endless amount of speed boosts for a limited time. Additionally, in Mario Kart: Double Dash!!, it is Toad and Toadette's Special item (with Petey Piranha and King Boo also being able to get it, since they can use any special item). The Golden Mushroom's initial appearance is a glowing gold Mushroom, but since Mario Kart: Double Dash!!, it has been given a gold crown with red jewels as well. This item was originally going to be in Mario Kart: Super Circuit, but never made it to the final game.
The Golden Mushroom makes an appearance in Mario Kart Arcade GP under the name Miracle Mushroom. It is one of Toad's special items, and it grants the user invincibility, as well as the ability to knock over any rival karts they run into, for five seconds. The Miracle Mushroom is functionally identical to the Star. A variant of the item known as the Miracle Mushroom+ exists. This variant extends the duration of the invincibility.
The chance of obtaining a Golden Mushroom is more common in Mario Kart 64 than in later installments, where it can be obtained from second to eighth place. In the game, players can obtain the item in second place, although this usually only happens when the first-place player is very far ahead of the second-place player. Triple Mushrooms are also more common to obtain in second place than Golden Mushrooms. It can be obtained in 6th to 8th place in Mario Kart DS, 6th to 12th place in Mario Kart Wii, and 5th to 8th place in Mario Kart 7.
In Mario Kart 64's Operation Card, the Golden Mushroom is called Super Mushroom. In the European version of Mario Kart 7, it is called Golden Dash Mushroom.
Mario & Luigi series
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 and Cheesy Drumstick replace the Golden Mushroom and in Mario & Luigi: Dream Team and Mario & Luigi: Paper Jam, they are replaced by various Candies.
Mario Party series
In Mario Party 2 and 3, the Golden Mushroom is an item that allows players to roll three Dice Blocks on their turn. It is stated to be Mario's favorite item in the latter game. Rolling three of the same number earns the player 20 Coins, and in Mario Party 3, rolling three sevens earns the player a 50 coin bonus. In these titles, the Golden Mushroom lacks its crown and has white spots and a tan body, appearing more like a yellow Super Mushroom.
In Mario Party: Island Tour, Star Rush, The Top 100 and in Super Mario Party, an identical item known as the Golden Dash Mushroom lets the player add five spaces to their roll. In Mario Party 10, players can get Golden Mushrooms in their carts to score three points in the minigame Movin' Mushrooms, and in Mario Party: Star Rush, players have to sort between Mushrooms and Golden Mushrooms in the Coin Chaos minigame, Conveyor Meltdown. The Golden Mushroom takes on its more traditional appearance starting with Island Tour.
Captain Toad: Treasure Tracker
Golden Mushrooms, referred to as Gold Mushrooms, appear as rare collectables in some courses in Captain Toad: Treasure Tracker, looking and acting as they do in New Super Mario Bros. 2. These mushrooms are usually a secondary objective in the courses they appear in. Some Gold Mushrooms can only be found through invisible Pluck Patches, which can be seen once Captain Toad approaches it, or reveals them with his headlamp.
Mario vs. Donkey Kong: Tipping Stars
Puzzle & Dragons: Super Mario Bros. Edition

Blocks or dropped after defeating some enemies with a 10+ combo, such as 2-Goomba Towers and Paragoombas. There is an even rarer variation called Grand Gold Mushroom.
Mario & Sonic at the Rio 2016 Olympic Games
Golden Mushrooms, referred to as Golden Dash Mushrooms, appear as items in the 100m Plus event in the Nintendo 3DS version of Mario & Sonic at the Rio 2016 Olympic Games.
