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 could also be crafted (in an unconventional manner) by placing crafted stone brick stairs near 3 leaf blocks will produce mossy stone brick. Likewise placing crafted stone brick stairs near 3 cobblestone blocks will produce cracked stone brick.
