A's Apocalypses: shroom doom
by awwshoot
A's Apocalypses: shroom doom adds a spreading mushroom threat to the overworld, where overgrowth mushrooms take over the surface of a world.
What it does
Megalium, a more virulent form of mycelium, spawns in temperate biomes and spreads across the ground. Overgrowth mushrooms then grow from it and rot the trees on the surface, so the fungus can take over large areas of a world over time. Players who do not want the surface changed permanently should be aware that the overtaking is not reversible in this mod. The code is under the MIT License and is open source, and the mod runs on client and server, so both the server and every player need it. It is published for NeoForge only, with files covering 1.21.1 – 1.21.11.
Key features
Spreading mycelium
Megalium spreads through temperate biomes and turns the ground into a fungal surface that keeps growing.
Rotting trees
Trees on the overworld surface decay as overgrowth mushrooms appear on them and where they are placed.
Irreversible overgrowth
Once fungi have taken over a surface, the change is permanent, so worlds should be backed up before use.

What the author says
Adds Megalium, a more powerful and virulent version of mycelium, which will spawn in temperate biomes and spread across the surface, rotting out overworld trees and growing mushrooms in their place. Needless to say, do not use this mod unless you are okay with your surface being irreversibly overtaken by fungi.
