Mossy Stone Brick

Mossy Stone Brick is a new block type that was implemented in the 1.8 Beta update. Mossy Stone Brick is one of the main components that make up Strongholds, which were also added in the 1.8 update. It can also be crafted (in an unconventional manner) by creating stone brick stairs, and mining them while they are not touching stone (this produces different results), and are near water.
