MycoMayhem is a chaotic mushroom-powered expansion that transforms Minecraft’s fungi into tools of survival, combat, building, and bizarre cuisine. In this world, spores aren’t harmless they’re power.
At the core of the mod is a new fungal progression system. Using the Mushroom Mutator—crafted with 2 iron ingots, a brewing stand, and 2 red mushrooms—you can create two unique mushroom types: the Puffball Mushroom and the Glowshroom. These strange fungi unlock everything the mod has to offer.

From these, you can forge shroomite, a powerful material created using 1 glowshroom, 1 diamond, and 1 iron ingot. Shroomite is the backbone of your gear and survival.

The highlight is the Shroomite Sword—crafted with 2 shroomite ingots and a stick. This isn’t just a weapon. Right-clicking launches you backwards, letting you escape danger instantly in a burst of fungal energy (with a cooldown, so timing matters).

For utility, equip the Shroomite Hat, which grants Haste and Night Vision, turning you into a fast and efficient underground explorer.

MycoMayhem also expands your building options with a full Glowshroom wood set and decorative tiles, letting you create eerie, glowing fungal structures.
And of course, the food:
Glowshroom Stew: grants Glowing and Haste, making you visible but faster.

Puffball Stew: a stronger, more nourishing version of mushroom stew.

Whether you’re crafting powerful gear, escaping danger with spore-fueled mobility, building glowing mushroom bases, or experimenting with strange new foods, MycoMayhem brings chaotic fungal energy into every part of your world.
Embrace the spores.
