In Super Mario RPG: Legend of the Seven Stars, a basic Mushroom recovers 30 HP for one party member. This mushroom had a red and white cap with an orange stem (and no face). However, Mushrooms that are found in Treasure Boxes recovers all HP and FP for Mario's entire party. These Mushrooms are used as soon as they are picked up. Additionally, these powerful Mushrooms have faces.

During the events of Mario & Luigi: Partners in Time, a Mushroom recovers twenty HP for one ally.
