Fungal Forest

After watching a few things with Paul Stamets and how he explained the interconnection between forests and fungi and his story about the Japanese scientists using fungi to find more efficient paths for subway trains, I realized that Minecraft is woefully lacking when it comes to incorporating the potential complexities of fungi.  

I request more advanced scripting for the Mycelium, allowing it to spread more prolifically, interconnect that which it spreads to, and benefit the flora by helping to fertilize the forest.  It should be found layered under the forest floor, and connect each tree to each other in a large fungal network. Plants growing over mycelium should grow larger than other trees of the same type and faster as well.  Crops could be planted over mycelium, resulting in more bountiful harvests, more often.  The mycelium should spread across the land (under ground) to other forests, tying them all into one biome (or sub-biome) stretching across multiple biomes.  

It would also be nice to be able to propagate this sort of biome.  Perhaps by planting mushrooms on a 3x3 or 4x4 area of mycelium, one could grow a giant mushroom which would act as a mother/hub for the fungus to inoculate a forest and begin to spread mycelium. Voraciously at first then more slowly as its reach becomes spread thin; until a new giant mushroom grows at the edge of the other's effective range, and begins the process of spreading mycelium anew.

It would be really fun if inoculated forests didn't stop growing out of control, albeit slowly.  This way, over time you would end up with beautiful and fanciful, even enchanted looking overgrown forests filled with gnarled trees and wild looking mushrooms which can be used for all sorts of different things from armor to potions to food.
