Add support for wood cutter mod:
https://www.curseforge.com/minecraft/mc-mods/corail-woodcutter

• Recipes for wood cutters (sawmills) are missing for mushroom wood
• Wood Recipes for mushroom wood inside a sawmill are missing

Maybe open an issue in the repository of the mod, because it has already mod support for other mods. :) But wait until more wood types are included.

Wood types are supported. only oak sawmill can be crafted out of mushroom wood. works.
