Fungus
Weird Fungus, Green Fungus, and Mystery Fungus are powder materials found in various biomes around the world.
Behaviour
Most fungus variants, if ingested, cause you to receive the 
Tripping status effect. This causes visual and aural distortions. If further amounts are ingested, the distortions increase, and at high levels of the Tripping status, strange eyes will open and close at random in the background, with an accompanying sound effect. When the tripping status progresses to Tripping balls (180s), a Fungal Reality Shift will occur.
Fungus is highly flammable and will quickly burn away if exposed to Fire or Lava.
All powder variants of Fungus have a very rare chance of appearing as a random material potion in a Treasure Chest or Great Treasure Chest.
Weird Fungus
Weird Fungus is an odd pink material that can most commonly be found in the Fungal Caverns and Overgrown Cavern, because it grows quickly from the Fungal Soil found there. It can be easily walked through, although it does not provide air and can cause suffocation if one remains inside it for too long.
Unlike most materials, it will slowly grow upwards, usually forming slender columns. If a moderate amount falls down due to the ground beneath it being destroyed, the movement seems to accelerate its growth, quickly generating massive spires of pink fungus. Pouring it from a Powder Pouch from great height can create massive towers of fungus.
Aside from the Fungal Caverns, it also has a chance to appear in a rare structure found in the Mines or in a random Powder Pouch on a pedestal.
Green Fungus
Green Fungus is a rarer variant of Mystery Fungus, and behaves in a very similar fashion. It can be found naturally lining rare cave structures in the Mines and Collapsed Mines.
Mystery Fungus
Mystery Fungus behaves very similarly to Weird Fungus, including the effect of ingesting it, with the additional quirk that it will convert many other liquids and powders into more of itself quite rapidly. It can be created by mixing Toxic Sludge, Fungus Blood and sand.
Fungus (Prop)
The Forest where the game begins features brown, salmon and sky-blue mushrooms on the surface and in caves. Smaller mushrooms also appear in the Mines. These are background elements and only become interactive if dislodged by damage. Eating them will inflict 
Food Poisoning instead of Tripping; however, they may be "ground up" into fungus blood in much the same fashion as worm corpses.
Weird Fungus (Corpse)
Weird Fungus can be found as the corpse of the following enemies.
Notes
- It is possible for a Fungal Reality Shift to remove both Weird Fungus and Fungus Blood from the game, making it harder to trip.
