Beta Mushroom Spreading
by NotSluggas
Beta Mushroom Spreading reverts how red and brown mushrooms spread to the Beta Minecraft behaviour, letting them fill an area without the limits of modern versions.
What it does
In modern versions, red and brown mushrooms spread only to a few nearby blocks, and only when a small number of mushrooms of the same kind sit in a limited nearby area. This mod changes that rule so mushrooms can keep spreading, which matches how the feature worked in Beta Minecraft. Players who remember the older behaviour will see the same spreading pattern, while the other mechanics of the game stay as they are.
The mod changes how far mushrooms spread, not how quickly they spread. Because mushrooms can keep growing, the Nether and caves can end up covered with them, and a world may come to look as if it were filled to the brim with mushrooms. The mod is server-side only, so only the server needs it. Installation requires Fabric API. The mod is published for Fabric and for 26.2 only, with the 1.0.0 file from 2026-06-25 as its latest release.
Key features
Unlimited mushroom spread
Red and brown mushrooms keep spreading across suitable blocks rather than stopping after a small area.
Beta-style rules
The spreading follows the behaviour of Beta Minecraft, so mushroom growth matches older worlds.
Spread distance only
The change affects how far mushrooms spread, not how fast they do, so growth timing stays unchanged.
Nether and cave growth
Mushrooms can cover large parts of the Nether and caves, which is the visible result of the reverted rule.

What the author says
You probably clicked on this mod wondering what exactly it changes. In modern versions of Minecraft, Red and Brown Mushrooms will only spread if there are fewer than 5 mushrooms of the same type within a 9×9×3 area.
