Mushroom Forest
Surreal landscape of giant mushroom-like trees. Peaceful but deep. Good for Lithium and special resources.
Quick Info
Overview
The Mushroom Forest is a dreamlike deep-water biome where colossal mushroom-like trees rise from the seabed, their broad caps forming a dim, layered canopy. Bioluminescent spots fleck the trunks and floor, casting soft light through the cool water and giving the whole region an otherworldly calm. With no major predators, it is one of the safest deep biomes in the game.
That safety makes the Mushroom Forest an ideal Lithium farm. Lithium deposits are common here, far more reliable than the rare nodules found in the Grassy Plateaus, and the surrounding outcrops still yield Copper and Titanium for general crafting. Players pushing into mid- and late-game recipes that demand Lithium will want to make repeated trips.
The catch is depth. At 150 to 300m the forest demands better oxygen management than the shallows, so a Seaglide and an upgraded oxygen tank are strongly recommended. Wreck fragments scattered among the trees reward scanning with advanced blueprints, making each dive doubly productive. Treat the Mushroom Forest as a peaceful, high-value waypoint on the way to even deeper regions.
Resources Found Here
The Mushroom Forest is the game's premier Lithium source. Deposits are scattered generously between the giant trees, while standard outcrops continue to provide Copper and Titanium so you never run low on basics while farming deeper materials.
Creatures Found Here
The Mushroom Forest is populated entirely by passive fauna. There are no major predators here, which is what makes it such a forgiving place to harvest Lithium and scan wrecks at depth.
Exploration Tips
Bring a Seaglide
The forest is large and deep. A Seaglide lets you cover ground quickly and reach the surface fast if your air runs low.
Upgrade your oxygen tank
At 150–300m, air is your main limit. An upgraded tank doubles your effective harvest time per dive.
Farm Lithium in bulk
Lithium is plentiful and used in many advanced recipes. Stock up in a single trip so you don't have to return often.
Scan the wreck fragments
Wreck fragments tucked between the trees unlock advanced blueprints. Prioritise scanning on every visit.
Points of Interest
Large Mushroom Trees
The towering mushroom-like trees define the biome. Their caps provide vertical navigation landmarks and their bases hide dense Lithium deposits.
Wreck Fragments
Scattered wreckage yields scannable fragments that unlock advanced blueprints, making each dive as rewarding for tech as for materials.
Map Locations
The Mushroom Forest sits beyond the Grassy Plateaus at mid-to-deep depths. Use the interactive map to pin Lithium clusters, mark wreck fragments, and chart oxygen-safe routes back to shallower water.

Frequently Asked Questions
Is mushroom forest safe?
Yes. The Mushroom Forest has no major predators and is one of the safest deep biomes in the game. The main challenge is depth and oxygen management, not hostile creatures, so it is a comfortable place to harvest Lithium and scan wrecks.
What resources are in mushroom forest?
Lithium is the headline resource and is abundant here, making the forest the best place to stock up. Outcrops also supply Copper and Titanium so you can keep your basic crafting stocked while farming deeper materials.
How deep is mushroom forest?
The Mushroom Forest spans roughly 150 to 300m. A Seaglide and an upgraded oxygen tank are recommended to explore comfortably, since air management rather than predators is the main constraint at these depths.
