Shroom

Shrooms are a group of decomposers and parasites that originated from the stickyballs. They have some outer physical resemblance to earth's mushrooms, though they are in fact quite different.

Anatomy
Most shrooms are built of two major parts, the stalk, and the cap. They also grow their spores from below the cap, sometimes from tiny sprouts and other times directly from it. Like the Terran mushrooms they resemble, they have fairly set anatomy which can be modified but will usually still contain a distinct cap and stalk.

Behavior
The diggerundi, a species of tiny colonial creatures, grow the shroom in their underground burrows. They do so by watering them from the water-tables and feeding them with their own feces. They later feed on them.

Diet & Energy
Originally most shrooms were parasites, growing directly from flora, mainly the tree plents, and feeding on their photosynthetic products. A specific line of shrooms evolved to become decomposers like their ancient ancestors. These started growing on the ground instead. After the gamma ray disaster, the only shrooms that survived were decomposers. These later diverged into many new forms.

One shroom was a parasite of fauna. This was the insanseshroom, which fed on small invertebrates.

Locomotion
Most shrooms are immoble, moving only if they infect moving organisms.

Reproduction
All shrooms use asexual reproduction method. They do so both by very fast asexual budding and very resistant spores like most descents of the stickyballs do.
