The Mushroom Forest in Subnautica is one of the biomes you recognize almost immediately. Giant mushroom-shaped structures grow on top of thick rock formations that look like underwater trees. According to the in-game idea behind the biome, these formations aren’t actually plants at all. They’re supposed to be a strange type of coral that grows into massive tree-like shapes.

The scale of these structures is pretty surprising. The mushroom “trees” stretch high above the seafloor, which means you can sometimes spot the biome even from shallower water while exploring nearby areas. Still, the actual floor of the Mushroom Forest sits much deeper. Most parts of the biome lie somewhere between about 125 and 200 meters.

That makes it noticeably deeper than places like the Herbal Plateau or the Kelp Forest, so you may not be able to stay there very long in the early game. That is why you need a Seamoth to explore the Mushroom Forest.

In this guide, we’ll go through the main things you should know about the Mushroom Forest. That includes where to find the biome, how to reach it safely, and what kinds of resources you can collect while exploring the area.

What is the Mushroom Forest in Subnautica

In Subnautica, the Mushroom Forest is a biome where you'll start drifting once the early game exploration phase begins to expand a bit. After spending time around the Safe Shallows and nearby kelp areas, you tend to wander farther out looking for wrecks and fragments. That’s often when you find the Mushroom Forest.

One reason players end up here fairly early is the technology scattered around the area. Parts for the Cyclops submarine and Moonpool are located in this biome, so it becomes a natural place to search once you start thinking about building larger vehicles.

The layout also feels different compared to some other regions on the planet 4546B. There’s quite a bit of open space between the giant mushroom structures, so swimming around doesn’t feel cramped the way it sometimes does in the Kelp Forest. At the same time, those huge formations stick out so clearly that they work almost like navigation markers.

Because of that mix of fragments, wrecks, and relatively manageable terrain, the Mushroom Forest tends to become one of those places players return to several times during the mid part of the game. Not exactly the first biome you explore, but not something reserved for the late game either.

Where is the Mushroom Forest?

To mark locations in the game, you need a coordinate system, and you have two options: console coordinates or home beacon triangulation. You can use whatever you want.

The easiest way is to use the first method. Everything in Subnautica has in-game coordinates. You can find the coordinates by pressing the F1 key to open the console menu. Below “Camera world pos” you will see three numbers labeled (x, y, z), where X is east-west, Y is depth, and Z is north-south.

To find the Subnautica mushroom forest location, you need to go to the coordinates: 529, -175, 371.

There are two separate mushroom forests, and they stand out strongly: tall trees of flat, disc-shaped mushroom-like branches. This is one of the best biomes to explore, and one of the first places to find large deposits of minerals. Once you have the drilling equipment, head into the mushroom forest to dive into your search for crafting materials.

Mushroom Forest Map

Another way to spot the Mushroom Forest in Subnautica is to sail along the Aurora (huge crashed ship). You can see on the map above that the Mushroom Forest is very close to the Aurora.

However, if you haven't figured out the radiation near the ship yet, I suggest keeping your distance.

Mushroom Forest Wreck

The Aurora Wreck is a part of the ship that you can only find after it explodes. A small amount of this debris can be found in the vicinity of the starship’s impact area, but most of them are still much further away.

You can find a wreck on coordinates: -630, -125, 752.

Despite this is not one of the largest wrecks in the game, it is split into two parts that are not related. If you are not careful to explore both areas, you will miss out on finding some blueprint fragments.

The wreck has several entrances: 2 at the bottom and 1 at the top. Moreover, there are a lot of useful fragments and parts in both sections of this wreck, so search it properly!

The most useful objects that can be found in mushroom forest wreck are:

Energy Cell Charger
Energy Transmitter
Multipurpose Room

Lifepod 13

Lifepod 13 is one of 8 crashed escape pods that can be found. The capsule can be found independently, or by a radio signal, which will be added to the PDA after receiving a radio message from the crew of this capsule by radio.

The lifepod is located at a depth of 180 m. To safely reach the pod, you need additional Oxygen Tanks or a Moth.

Coordinates of Lifepod 13 in Mushroom Forest: -919, -177, 508.

Lifepod 13 Loot

On board the capsule there was one passenger, the emissary of the insurance department of the Torgal corporation of the trans-state of the Independent Mongolian States – Jochi Hasar, who was carrying out a special mission on the expedition.

From the magazine, you learn that the emissary prayed during the fall of the capsule. By the time the capsule was discovered, Jochi Khasar had already died. You will find the lost PDA Voice log of the emissary from capsule 13.

Not far from the Lifepod 13 in the area of the Western Mushroom Forest, you can find:

Giant size Mushroom tree at the roots of which has an entrance to the cave (Next to the capsule)
A canyon begins on the bottom surface, which serves as a threshold to the entrance to one of the Alien caches (120 m south of the capsule)

Cyclops Fragments

In order to create a “Cyclops”, you need 3 types of blueprints for the engine, hull, and bridge. Some of them you may find in the Mushroom Forest:

2 Hull Fragments
2 Bridge Fragments

You can find most of the parts around the Lifepod 13 as they are the easiest and safest to find.

Moonpool Fragments

There are 2 Moonpool fragments that you can find in the Mushroom Forest Biome and scan. They are located at depths of 150m and 160m.

Mushroom Forest Resources

In the Mushroom Forest, you can find many useful resources that will come in handy for crafting in the future. Moreover, apart from the various fragments mentioned above, you can find some useful plant seeds, as well as fish eggs.

Materials	Seeds	Creature Egg
Diamonds	Climbing Algae Seed	Boneshark Egg
Gold	Vein Nettle Seed	Jellyray Egg
Acid Mushroom	Dwarf Fan Seed
Cristal Pitchlende	Blue Palm Seed
Salt Crystal	Acid Fungus Spore
Lithium	Gel Sac Spores
Mushroom Sample
Plate Coral Sample
Ruby

Flora, Fauna and Corals

You will come acrossunique representatives of flora and faunain the Mushroom Forest. In some places it can even be dangerous, so be on the alert!

Moreover, here you can find some types of corals. Some of them are purely decorative, but some can give you useful resources.

Flora	Fauna	Corals
Acid Mushroom	Ampeel	Brain Coral
Grue Cluster	Boneshark	Jardi's Tung
Pygmy Fan	Jellyray	Slanted Shell Plate
Tree Leech	Mesmer	Tree Mushroom
Treespawn	Peeper	Table Coral
Veined Nettle	Reefback Leviathan
Writhing Weed	Shoal of Fish
	Spadefish

You can also find such rocks in the mushroom forest as:

Limestone
Sandstone
Purple bump
Slate

Subnautica Mushroom Forest Cave

In the Forest of Mushrooms, you can find a giant coral tree with tunnels in its trunk leading into a network of unique caves. They are distinguished from the rest by the characteristic Blue Clusters, which grow in rows of glowing tubes. These rows run along the corridors, so they can be used for orientation in space.

The caves are large enough for the Seamoth submarine to squeeze through. But this is typical for entrances, you will have to swim into the side corridors without equipment. Besides the large coral tree, there are other entrances.

The caves do not differ in a special variety of flora and fauna, but you can find lots of clusters of glowing Grue plants. Moreover, here you can mine gold and lithium.

In the depths of the cave, in its largest part, there is a hidden egg of a cute creature. You can also find a similar egg in the western Mushroom Forest in Subnautica.
