Fungus

Green fungi will be needed to make any of the colored fungi. All basic fungi doesn't really have a purpose except to grow and keep growing unless boxed in. Basic fungi will replace liquid and weak blocks. Breaking fungi with your hand can drop a slimeball, using a sword will drop the block itself. Basic Fungi have two types the normal and rapid, rapid grows faster.

Colored fungi are just colored versions of the green variety. Grows unless enclosed, replaces liquid and weak blocks, breaking fungus with a hand can drop a slimeball, breaking them with a sword, shears, or silk touch drops the block itself, and their are two types normal and rapid which rapid grows faster. The colors to choose from are RED, GREEN, BLUE, PURPLE, YELLOW, ORANGE, PINK, CYAN.

Building Fungi as the name suggests build different types of blocks. THese include block builders which build blocks as they grow but will not grow higher than you placed the blocks. Layer builders build a flat layer of the block specified. And liquid builder are just block builders but for lava and water. Building blocks include Netherrack, Sand, Dirt, Stone, Cobble, StoneBricks, SandStone, Glass.

An experimental builder is the maze builder which when placed will start to build a maze. Like the other building fungi it will not grow upward but only down and to the sides.

Acid fungi are fungi that kill other fungi their are two types the regular and the rapid. One is all you need for a big group of fungi.

Another variety of fungus are the block eaters which eat a certain type of block by replacing the blocks they eat with themselves. The eater types are Stone, Rock, Dirt, Sand/Gravel, Leaves/Water, and one to target Forests. All eater types are configurable for which types of blocks they eat.

A sub-species of the Block Eaters are the vertical eaters which instead of growing in any direction will not grow any lower than where they were placed. All eater types are configurable for which types of blocks they eat.
