Soft, squelching footfalls and a strange, moldy odor indicate that some creature is nearby—but nothing can be seen.
This creature looks like a brown and greenish-brown mass with a cluster of nodules atop the main mass, though it is visible only when dead. A cluster of nodules atop the main mass serve as sensory organs. The creature feeds and attacks with a gaping maw lined with rows of teeth. Four stumpy legs support the creature and allow it to move about.
This ambulatory fungus is naturally invisible, making it a feared predator among subterranean inhabitants.
Combat
A phantom fungus usually roams quietly, hunting for prey. It attacks lone individuals almost anywhere, but when tackling groups it prefers an open space where it has a better chance.

Special Abilities
Alien Mind (Ex)
Phantom fungi get a +8 bonus to saving throws against mind-affecting effects, as their perceptions and mentalities are so different from those of humanoids as to be nearly unfathomable.
Greater Invisibility (Su)
This ability is constant, allowing a phantom fungus to remain invisible even when attacking. It works like greater invisibility and lasts as long as the phantom fungus is alive. This ability is not subject to the invisibility purge spell. A phantom fungus becomes visible 1 minute after it is killed.
Skills
A phantom fungus has a +5 racial bonus on Stealth checks to move silently.
