Subnautica 2 Tallshroom Guide

Where to find Tallshroom in Subnautica 2, how to scan or harvest it, and when it matters for routes, resources, or adaptations.

Tallshroom quick answer

Tallshroom is a fungal flora entry associated with Root Canyon. Treat it as a route marker first and a harvest target second; many bad plant routes start when players gather before they know the recipe need.

Location and route

Approach Tallshroom from a known oxygen point, scan the plant, then check the floor, walls, and nearby fauna before harvesting. If the plant sits in Root Canyon hazards, mark it and return with the right tool instead of forcing the route.

Uses and unlock value

The practical value is landmark, possible growbed planning. If it supports a recipe, collect only the amount needed for the next craft. If it is a landmark, use it to label the route and connect it to the nearest biome or resource loop.

Risk and scan notes

Great beacon candidate for canyon routes. In co-op, call out the plant name, region, and nearest return marker so teammates can reuse the route without duplicating the scouting work.
