The Fungal Hall B is a room in the Phazon Mines, in the game Metroid Prime. It is comprised of very large Saturnines and a floor full of Phazon. There are several Metroids in this room, as well as a Glider, which Samus must grapple on to in order to progress. Because this place is very dark, the Thermal Visor can improve vision. This room connects to a Missile Station.

- Missile Station Mines (via Red Door)

- At the far end of the room, there is a circle of small Saturnines. If Samus lays a bomb here, the floor will crumble and the expansion will be revealed.
