Describe the bug
The red, brown and green mushrooms, the wood blewits, the death caps, the weeping milkcaps and the soul shrooms in the Wailing Garth biome, and likely other biomes that use them, use their outer texture on the inner parts of the mushroom, when vanilla large mushrooms use the beige inner texture there instead.

To Reproduce

• Create a new world.
• Travel to a Wailing Garth biome.
• Look underneath the mushrooms.

Expected behavior
The mushrooms in the Wailing Garth biome and other BYG Nether biomes would have the beige inner texture on their inside areas to match vanilla large mushrooms.

Intentional behavior unless youd like to rewrite our mushroom generating code :)
