I have realized that when i find mushroom forests it seems weird that they are in the sun.
I find that it would be a lot more fun and exciting to find them underground.
The schematic for an underground shroom forest is out now.
Here is the link: http://www.planetminecraft.com/project/the-underground-mushroom-forest/
Maybe in the future i will come out with mod that will generate it and also add a few extra mods.

I would love to see this change in Minecraft and with enough support maybe it is possible.
