Fungi, Plants & Immobile Invertebrates:
Crimson Husk Root:
This form of vegetation lays dormant across plains, waiting for creature to die near it. Within a matter of hours the roots creep though the soil and sprout fast growing vines though the corpse leaving a husk of dried flesh & bones as it consumes the water and nutrients from the body. Within less than 24 hours, it blossoms spreading it's pollen across the plains, then goes dormant again.

Bone Mushrooms:
These columns interesting enough are not actually mushrooms or bone, but a bizaar form of land based coral that builds up over sources of underground water and channel the water up though the colony. They also feed on the insects and other small organisms that are drawn to the water.

Stone Mold or Bone Spores:
This is a type of fungi that tends to grow into strange skeletal yet pourous shapes in the wild. Uncontrolled some of these forms appear to be fractal patterns made of bone shapes. Some Sorcerers and Psychics have found methods of manipulating these growths over time into buildings, statues and furniture. Some say that the old races built many of their ancient structures via these methods.
