MycoMayhem
by Glowy
MycoMayhem is a NeoForge expansion for 1.21.1 that builds a mushroom-powered progression, with tools, armor, food and blocks drawn from fungi.
What it does
Crafting a Mushroom Mutator from two iron ingots and two red mushrooms on a brewing stand produces two mushroom types, Puffball Mushroom and Glowshroom. Those fungi start the mod's fungal progression, which the author describes as a new system. Spores found in the world are not harmless and can affect the player.
Shroomite is a material forged from one Glowshroom, one diamond and one iron, and it forms the basis of the survival gear. A Shroomite Sword is crafted from two Shroomite ingots and a stick. Right-clicking launches the wielder backwards in a burst of fungal energy, which then needs time to recharge, so timing matters when escaping danger. A Shroomite Hat grants Haste and Night Vision, which helps underground work.
No required dependency is listed for NeoForge. Installation covers the server and each player's game. Files cover 1.21.1 only, with 1.2 published on 2026-05-10 and the first release on 2026-04-25. MycoMayhem is not open source and is released under All rights reserved.

How it compares
Glowing Mushrooms is a NeoForge mod for 1.21.1 that is also client and server and not open source, under All rights reserved. Nether Fungi Stew is the same loader, version, environment and license, so it covers a different food set. Mushroom Fields is NeoForge for 1.21.1 – 1.21.4 and Fungiculture is NeoForge for 1.21.8 – 1.21.10, which means each targets a different version range than MycoMayhem.
