Mycelia
Mycelia is a hand-gathered organic crafting material, not a mineral node resource.
Search caves for mushrooms and other suitable fungal vegetation. Do not place a Miner or look for a powered extractor; gathering is by hand or Chainsaw depending on the plant. Take the collected material back to storage or to the crafting or production area where you need it.
Repeat gathering when your Fabric, inhaler, or Biomass stock falls below the amount needed for the next production run. Recheck the intended recipe before gathering if you are collecting for a specific crafting goal.
Stop collecting when the target crafting or fuel buffer is filled, or sooner if cave hazards make further gathering unsafe.
