Leaf litter alley

Leaf litter alley is a new biome that has more detris than any forest and has scattered pieces of wood. However, there are plenty of coal under the detris. The landscape is relatively distorted, and mushrooms are a common sight. Here ores are absent and in their block form. 

Cobblestone paths can also be seen regularly and bridges over rivers and secret underground bunkers. There are not randomly generated blocks of wood in the air: instead there are what seems like the remainder of trees. There is no dominant type of wood but all variants at once.  

The chances of finding this biome is slightly less than finding a mesa .
