A meaty bioengineered mushroom grown for its nutritious value. It can grow on fungal gravel, but only in darkness - exposing it to any kind of light, including darklights, will kill it.

Nutrifungus grows on lichen-covered soil and must be planted in and stay in complete darkness. So long as the darkness requirement is met, it can be grown in any terrain that is sufficiently fertile to support a growing zone. This includes, but is not limited to, fungal gravel and hydroponics basins. Due to its low fertility sensitivity, it takes fewer penalties from poorer soils than more sensitive plants, but also benefits less from being in hydroponics. Nutrifungus is immune to blight. An interesting exception to the rule that Nutrifungus can only grow in darkness is when planted around other mushroom-like emitters of light, such as Bryolux, Agarilux, or Glowstool.

Note that most ideoligions hate eating raw fungus.

  • Analysis[edit]

    Nutrifungus grows very slightly slower than potato plants, taking 103.4% the time to grow for the exact same yield. In addition, yield per work is identical between the two crops, making them mostly identical for the purposes of food. Nutrifungus has even less fertility sensitivity than potatoes, so it actually grows faster in poor soil (the potato plant's usual niche).

    However, a baseline pawn will work 80% as fast with fungus due to the penalties of darkness. The Lighting: Darklight Preferred precept or Dark vision geneContent added by the Biotech DLC both counteract any negative dark-related effect.

    In addition, most ideoligions dislike eating raw fungus, with a −3 moodlet when cooked. This makes potatoes the superior overall choice for colonies without the Tunneler meme, so long as you can grow outdoors. With the Tunneler meme, growing nutrifungus becomes a no-brainer, as tunnelers hate non-fungus vegetables. They can be also viable if you are forced to grow crops under gravel or stony soil, such as in the Extreme Desert.

    Indoor farming[edit]

    Even without the Tunneler meme, fungus can be worthwhile to sow. This is because nutrifungus can be grown in darkness, which lets you grow indoors without needing a sun lamp. Being indoors, in turn, lets you use heaters to control the temperature, and grow crops during the winter. So, even when considering the mood penalty of fungus, and the work penalties of darkness, this crop can be worthwhile to grow. Also since it grows in caves it considerably harder for raiders to set alight than other chemfuel feedstocks.

    It can also be grown freely if you are forced to (or want to) live under a sun blockerContent added by the Royalty DLC. With a sun blocker, you'll still need to place a roof over the growing area for colonists to actually plant the crop.
