Origins
The Super Mushroom made its debut in Launch Title Super Mario Bros. for the Nintendo Entertainment System. It's become a staple of the 2D Super Mario series since then.



It functioned as it does in Super Mario Bros. and the other games it appeared in, though the Power-Up tiering system in Super Mario Bros. would make it so that if you had taken damage with a Tier 2 Power-Up like a Fire Flower, you would not turn back into Super Mario, but rather Mario, unlike Super Mario Maker Series' Super Mario Bros. 3-based tiering system.

Its abilities in the Game Style originated in 2006's New Super Mario Bros. for the Nintendo DS and has been a staple in the New Super Mario Bros. series and was reintroduced in the Super Mario 3D World game and its respective Game Style in Super Mario Maker 2.

Breaking Brick Blocks
In all Game Styles, the Super Mushroom will grant you the ability to break Brick Blocks from below.

In the Game Style and the  Game Style, you have the ability to break Brick Blocks from above with the use of a Ground Pound.

In the Game Style, Super Mario is able to break that Game Style's equivalent of Brick Blocks (being Spinning Blocks) by spinning on them.

Increased Height
When becoming Super Mario, Mario becomes 2 blocks tall, but Mario can crouch, becoming only a block tall.

Trivia

 * Despite the Super Mushroom lacking its eyes in the original Super Mario Bros., the Japan-Exclusive sequel to it (also known as The Lost Levels) which follows the same art style as its predecessor, has The Super Mushroom appear with its eyes, predating its more well known appearance with eyes in Super Mario Bros. 3.
