Add in an option to turn off or remove huge mushrooms in the config file. Currently, there's no easy way of removing the huge mushrooms while Dynamic Trees is installed. This creates compatibility issues with mods that control world generation.

Something like this in your config/dynamictrees/worldgen.json file should disable giant mushrooms in mushroom type biomes:

[
  {
    "select": {
      "type": "mushroom",
      "name": "minecraft:.*"
    },
    "apply": {
      "cancelvanilla": false,
      "chance": 0
    }
  }
]
