No Glow Lichen is a lightweight Fabric mod for Minecraft 1.21.11 that completely removes Glow Lichen from your game world.

It is designed for players who do not want Glow Lichen appearing in caves, terrain, structures, or modded biome content. Unlike a simple datapack, this mod is meant to be a more universal and reliable solution.

Features

- Removes existing Glow Lichen from chunks as they are loaded

- Prevents new Glow Lichen from remaining in newly generated chunks

- Blocks manual placement of Glow Lichen

- Handles waterlogged Glow Lichen safely by preserving water instead of leaving unwanted air gaps

How it works
When a chunk is loaded or generated, the mod scans it and removes any Glow Lichen it finds. This means already existing worlds are supported as well, but old chunks must be loaded at least once before their Glow Lichen is cleaned up.

Performance
The mod is designed to avoid heavy long-term overhead. Chunk cleanup is processed gradually so it does not permanently impact performance during normal gameplay.

Compatibility

- Fabric

- Minecraft 1.21.11

Notes
This mod is intended to be a simple, focused solution: no config bloat, no extra features, just a world without Glow Lichen.
