Mossy Stone Brick

Mossy Stone Brick is a variant of a Stone Brick, a block that was implemented in the 1.8 Beta update. It can be found in Strongholds, which were also implemented in the 1.8 update. Its texture is a stone brick texture modified to add a mossy effect, much like mossy cobblestone.

Trivia

 * Due to a bug in 1.8, Mossy Stone Brick could be made by destroying Stone Brick Stairs that were facing east (common north is where the sun rises)
