Myceliosphere (Moar Shrooms!)(addon to cave update?)

With the new editions to the nether bringing along new mushrooms we now have 4 variants of mushroom which by it's self is pretty epic, but what happens when the nether a generally hostile area merges with the mooshroom biome I very peaceful area? Well, the Myceliosphere of course. The myceliosphere will generate as high as y 40 and below, and will have a giant bubbly shaped cavern filled with dark mycelium. Dark mycelium will be a dark purplish hue and the sum of its nylium and mycelium brothers it will spread to nearby dirt in dark levels of light. It will be populated with many darker hues of shroom with the occasional oddity of a glowing shroom spread about. When glow shrooms grow these shrooms will turn dark mycelium around them into a purple glowing mycelium. Occasionally you will find burrow of shroomites these will be a crustaceous looking bug with a black shroom growing on their back. You can harvest this special black shroom cap with shears and it will slowly grow back but be careful they attack when you step to close to them. Running away will make them disengage but their pinch is imbued with a short withering like effect. The burrow can be picked up with silk touch. Without angering them so long as they are all in the burrow. And more rarely you come across an lichen shambler which spawn at start of the world so there are a limited number of these zomboid creatures.
