Where Do You Find Brown Mushrooms in Minecraft?

Brown mushrooms are one of Minecraft's most quietly useful resources — needed for fermented spider eyes, mushroom stew, and rabbit stew, among other crafting recipes. Yet they're easy to overlook if you don't know where to look. Unlike many resources, they don't follow a single biome rule or depth requirement. Their spawning logic is tied to light levels, not just location, which changes how you approach finding them.

How Brown Mushrooms Spawn: The Light Level Rule

The single most important thing to understand about brown mushrooms is their relationship with light. Brown mushrooms can only naturally exist and spread in areas with a light level of 12 or lower. In brightly lit overworld areas, they simply won't appear or persist unless placed by the player.

This is different from most blocks in the game, which are governed primarily by biome type or height. Mushrooms follow a shadow-and-darkness logic, which is why caves, dense forests, and specific biomes become reliable hunting grounds.

Reliable Locations for Finding Brown Mushrooms 🍄

Mushroom Fields Biome

The Mushroom Fields (formerly Mushroom Island) biome is the single most consistent source of both brown and red mushrooms. Here, giant mushrooms grow naturally on mycelium, and smaller mushrooms scatter across the ground freely — even in full daylight. Mycelium suppresses hostile mob spawning and allows mushrooms to exist regardless of light level.

The catch: Mushroom Fields are rare and usually generate as isolated islands surrounded by deep ocean. They're not a biome you stumble into during a typical playthrough.

Dark Forests (Roofed Forests)

Dark Forest biomes are probably the most practical overworld source for most players. The thick canopy of dark oak trees blocks sunlight enough to drop ambient light levels below 12, allowing brown mushrooms to grow naturally on the ground beneath the trees.

You'll typically find small brown mushrooms scattered throughout the forest floor, and occasionally giant brown mushrooms growing as part of the natural terrain generation. This biome is far more common than Mushroom Fields and usually accessible within a reasonable distance from spawn.

Caves and Underground Areas

Any underground cave system naturally qualifies — light levels underground default to 0 in the absence of torches or lava. Brown mushrooms generate naturally in caves as part of world generation, typically on stone or dirt floors.

Since the Caves & Cliffs update expanded cave systems significantly, underground mushroom hunting has become more productive. Lush Caves in particular generate with considerable ambient plant life, and both mushroom types can appear in cave interiors more frequently in these regions.

Swamp Biomes

Swamps are another overworld location where brown mushrooms appear. The combination of shaded areas under tree canopies and the general dimness of the biome creates enough low-light zones to support natural mushroom growth. They're not as densely populated here as in Dark Forests, but if you're exploring a swamp, checking the shadowed areas and under trees will usually turn up a few.

Nether Environments

Brown mushrooms also appear in the Nether, specifically on Netherrack surfaces in areas with low light. They're less common here than in the overworld, but if you're already operating in the Nether for other reasons, it's worth checking darker recesses. Giant mushrooms — both brown and red — also generate naturally inside Nether Wastes and certain other Nether biomes.

Growing Brown Mushrooms Yourself

Once you have even a single brown mushroom, you have options. 🌱

Spreading: Mushrooms slowly spread to adjacent blocks over time if the light level stays at or below 12. This is slow but requires no materials beyond the original mushroom.

Bone meal method: Applying bone meal to a brown mushroom planted on dirt, grass, podzol, or mycelium will attempt to grow a giant brown mushroom. The giant variant can then be harvested for 2–4 smaller brown mushrooms per attempt. On mycelium or podzol, mushrooms can be planted in any light level, making these surfaces ideal for indoor or surface-level mushroom farming.

Controlled farming: Many players build enclosed, torchless rooms (or use soul torches/tinted glass to control light) to grow mushrooms at scale indoors. The space and light management required varies depending on how many mushrooms you're trying to produce and whether you're playing Java or Bedrock editions, which have minor differences in spread timing.

Variables That Affect Your Search

How quickly and easily you find brown mushrooms depends on several factors:

What "Low Light" Actually Means in Practice

It's worth understanding that light level 12 is not as dark as it sounds visually. Torchlight reaches level 14 at its source and drops by one per block of distance. A room lit by a single torch still has low-light corners where mushrooms can exist. Overcast or shaded outdoor areas can hover around level 10–11, which is why dense forest floors work even without a cave.

Players who want consistent supply usually end up building dedicated mushroom farms once they locate their first specimen — the farming mechanics reward a small upfront investment with a reliable, renewable source. Whether that's worth doing depends on how heavily your recipes rely on mushrooms and how your base is already set up.
