I just wanted to suggestion to add netherrack mycelium that would cover the fungi forest biome like the overgrown netherrack does in undergarden. It would make the fungi forest biome more interesting and unique.

Thanks for adding it, I close the suggestion now. ;)

I reopen temporary the issue for noticing that it misses the mycelium particles for netherrack mycelium.
About block particles, the flesh haven't any more particles like in 1.7.10.
