Mycelium Slab

ModBetter With Mods
TypeSolid block

The Mycelium Slab is a slab added by Better With Mods. Mycelium Slabs are grown out of Dirt Slabs (surrounded by Mycelium) and can, in turn, turn regular Dirt Blocks into normal Mycelium Blocks. Mycelium Slabs can also be right-clicked with a Shovel to make Path Slabs.

Mycelium Slabs can not be placed in the top half of a block, however, placing a Mycelium Slab on top of another will turn them both into a single Dirt block.
