The 1-UP Mushroom is a green-topped mushroom that when picked up, grants the player an instant 1-UP, which is worth one Extra Life. It is one of the rarest mushrooms to find in every Mario game. They are usually in hidden or hard to reach places, though in Super Mario Galaxy 2, it can be brought to Mario or Luigi from a distance by the second player in co-op mode. They are usually found in hidden blocks also.
 Super Mario Series
 Super Mario Bros.
They would first appear in Super Mario Bros. were they moved like normal Mushrooms but take on a green and brown look. They are normally found in hidden blocks or in risky places that Mario will risk a life to gain a life. They can gain extra lives by gaining coins or getting the 2 hidden 1-Up Mushrooms in the level, more than any other world of the game.
 Super Mario Bros.: The Lost Levels
 Super Mario Bros. 2
Super Mario Bros. 2 would see 1-Up Mushrooms looking different from the green-capped mushroom. They are found by pulling a plant and have a solid red cap that says "1 UP" on their side.
 Super Mario Bros. 3
They would appear once again in hidden blocks or risky spots in Super Mario Bros. 3. They would include white spots on their green cap.
 Super Mario World
They would behave similar to they did in Super Mario Bros. 3 in Super Mario World. They appear more often in the game. Fishin' Lakitus often carry them as bait for Mario and will chase after him, throwing Spinys once Mario has taken the bait. They can also appear out of eggs when Mario is riding Yoshi and hits a ? Block that contains an egg.
 Super Mario 64
The 1-Up Mushrooms are the only type of Mushrooms that appear in Super Mario 64. They are found in various places like a ring of coins or collecting a ring of coins. They can be found in hidden areas or on top of poles. They will try to move away from Mario though some will follow Mario until he collects the life. Mario can also get an extra life by collecting fifty coins in level and then complete the level.
They would be the most common Mushroom in Super Mario 64 DS as Super Mushrooms would also appear in the game. There is three 1-Up Mushrooms on the top of Peach's Castle when the player uses the cannon to reach there.
The 1-Up Mushrooms are green with light green spots.
 Super Mario Sunshine
 New Super Mario Bros.
1-Up Mushrooms could be collected the same as they were in Super Mario Bros. in New Super Mario Bros.. They can also be obtained after Mario or Luigi have used the Mega Mushroom. Destroying a certain amount objects will cause the player to gain extra lives. They will fall from the sky and the easiest way to gain lives is to knock over the flagpole at the end of the level to fill it completely.
There are Toad Houses scattered around the game and some will contain 1-Up houses. Mario and Luigi will need to hit the blocks with 1-Up Cards. There is a Bowser Card in the mix of these cards and if it is hit, then the game ends but the player will acquire the blocks.
 Super Mario Galaxy
1-Up Mushrooms could be found in several places in Super Mario Galaxy. They could be found at the bottom of planets or close to Black Holes. When a player touches all Rainbow Notes that is activated by a ? Coin, then a 1-Up Mushroom will often appear. The player can also give the Luma Shop enough Star Bits so that it can transform into a 1-Up Mushroom. There is a total of five 1-Up Mushrooms on the Comet Observatory.
 New Super Mario Bros. Wii
Similar to their appearance in the first New Super Mario Bros., the ones in New Super Mario Bros. Wii can be collected in the same manner. There is a mini-game in the 1-Up Toad Houses called 1-Up Blast. Players will need to hop into cannons and aim at the balloons with numbers on them that range from one to four.
When Mario gets to ninety-nine lives, Mario will take off his hat and only will get it back when he loses a life.
 Super Mario Galaxy 2
1-Up Mushrooms would have the same effect in Super Mario Galaxy 2. They can be found after collecting all Rainbow Notes, Mario can often get a 1-Up Mushroom to appear and sometimes in three. Mario can also make 1-Up Mushrooms appear after collecting all of the coins that appear from the ? Coin. He can also get 1-Up Mushrooms from the Luna Shop on Starship Mario or from Chance Cubes.
 Super Mario 3D Land
In Super Mario 3D Land, 1-Up Mushrooms work like they do in any other Mario game. When a player reaches 1,000 lives, a crown will be shown, if they reach 1100, then two crowns will show and if they reach the max of 1,110 lives, then there will be 3 crowns shown and Super Mario will not wear his hat. When he loses a life, he will wear the hat once more similar to New Super Mario Bros. Wii
 New Super Mario Bros. 2
The 1-Up Mushroom will be appearing in the upcoming Nintendo 3DS game, New Super Mario Bros. 2.
 Mario & Luigi Series
1-Up Mushrooms would appear in Mario & Luigi: Superstar Saga, Mario & Luigi: Partners in Time and Mario & Luigi: Bowser's Inside Story. They are used to revive Mario or Luigi when they lose all of their HP in a battle. They are given half of their health back when they're revived.
The Mario & Luigi series would also have a stronger version called 1-Up Super that is seen in all three games. It will revive all of the HP of the Mario Bro(and BP in Superstar Saga). It would be renamed to the 1-Up Deluxe in Bowser's Inside Story and not restore SP in the game. They are expensive to buy.
