Mushroom Caverns

hi, I am very excited for the Cave update, so I think a Mushroom Cavern biome would fit perfectly. 

This biome would spawn in the mushroom biome and would have a larger entrance. it would be a very big cave and you would be able to fly threw it with a elytra! it could have new blocks, plants and mobs. some ideas for this biome are:

* large pink or blue mushrooms that could be used for brewing

*new mobs called Mushers could run around and eat up your items, they would hid and look like normal mushrooms, but when a item is drooped near them they would pop out of the ground and run away

*A new Mycelium that when walked on they glow

these are just some ideas, love what your doing Mojang. Keep it up!
