Nutrifungus can be grown in darkness, indoors, and in caves
Nutrifungus is a meaty, bioengineered mushroom grown for its nutritious value. It can be grown in darkness, allowing it to be grown indoors without the need for a sun lamp. This makes it a reliable food source, as it can be grown during winter and is less susceptible to raiders and blight.
Nutrifungus grows on lichen-covered soil and must be planted and remain in complete darkness. It can be grown in any terrain that is sufficiently fertile, including fungal gravel and hydroponics basins. However, it is sensitive to light, and exposing it to any kind of light, including darklights, will kill it. The only exception is when planted around naturally glowing mushrooms like Bryolux, Agarilux, or Glowstool.
The ability to grow Nutrifungus indoors provides several advantages. Firstly, it allows for temperature control using heaters, enabling growth during colder seasons. Secondly, growing Nutrifungus in caves or enclosed spaces makes it harder for raiders to set it alight compared to other outdoor crops. Additionally, the low fertility sensitivity of Nutrifungus means it can thrive in poorer soils, although it benefits less from hydroponics.
Nutrifungus is available to everyone and can be grown without fungal gravel. It can be grown at any tech level and does not require power, making it accessible to players regardless of their in-game progress or resource availability. The crop is particularly beneficial for Tunneller colonists, as it provides them with a mood buff.
While Nutrifungus offers advantages, there are also some considerations. It grows slightly slower than potato plants, and the work penalties associated with darkness can impact the overall yield. Additionally, the raw fungus creates a beauty penalty, and some ideologies express dislike for consuming raw or cooked fungus, resulting in potential mood debuffs.

Devilstrand Mushrooms can be unlocked by researching Devilstrand
Devilstrand Mushrooms are a unique type of crop in Rimworld that can be unlocked through research. These mushrooms are described as fragile and have been genetically engineered to produce a high-grade silk net, giving them a reputation for mystical properties. The in-game description hints at the greed it inspires in people, with its name being derived from this aspect.
To access the Devilstrand Mushrooms, players must first research Devilstrand. Once unlocked, these mushrooms can be grown in a designated growing zone. Each mature mushroom yields six devilstrand, depending on the harvester's Plant Harvest Yield stat. The fibres obtained from harvesting can be used as a substitute for cloth and animal skins, making them valuable for crafting clothing and other items. However, it is important to note that Devilstrand Mushrooms take a very long time to grow, which may deter some players from cultivating them.
Despite the lengthy growth period, Devilstrand Mushrooms offer significant advantages. They are the third-most protective textile in the game, surpassed only by Hyperweave and Thrumbofur. However, unlike Hyperweave, which is limited to trading, and Thrumbofur, which relies on the rare and slow gestation of thrumbos, Devilstrand Mushrooms can be easily farmed within your colony. This makes them a stable and preferred clothing textile for mid- to late-game colonies with the necessary time and research capabilities.
The exceptional beauty and market value of devilstrand fabric make it ideal for use in furniture, enhancing the quality of rooms. Additionally, devilstrand is the least flammable textile, tied with Hyperweave, offering superior protection against heat damage. While it may not be the most profitable crop due to its slow growth, devilstrand can still provide large amounts of money with each harvest, especially with skilled crafters.
Overall, Devilstrand Mushrooms in Rimworld offer a unique and valuable resource for players who are willing to invest the time and effort into researching and cultivating them. With their protective and aesthetic qualities, devilstrand fibres can enhance the functionality and beauty of crafted items, making them a desirable addition to any colony.

Agarilux is a wild mushroom that grows in caves and dies in the light
Agarilux is a wild mushroom that is unique to the world of RimWorld. It is described as a large, purple mushroom with glowing protrusions that make it beautiful to look at. However, this wild mushroom is quite peculiar as it only grows in specific conditions and environments.
Firstly, Agarilux is a wild mushroom that naturally occurs in caves. It cannot be cultivated or grown by players; instead, it only spawns organically within the game in underground cavernous spaces. This aspect of Agarilux makes it a unique and intriguing feature of the RimWorld ecosystem.
Secondly, Agarilux has a strong relationship with light. Despite being a glowing mushroom, it is highly sensitive to light exposure. In fact, exposing Agarilux to any kind of light will result in its death. This characteristic further emphasizes the importance of keeping Agarilux in dark, cave-like environments.
The growth of Agarilux takes approximately 60 days, which is considered a slow growth rate. Once fully matured, each Agarilux mushroom can be harvested for up to 35 raw fungus. Interestingly, Agarilux reproduces by spreading spores to nearby dark areas, ensuring the continuation of its species in suitable environments.
Agarilux is just one of the many mushrooms that can be found in RimWorld. Other notable mushrooms include Nutrifungus, Devilstrand Mushroom, and various mod-added mushrooms that expand the underground ecosystem of the game. The existence of these mushrooms adds depth to the game's world-building and provides players with unique resources and challenges.

This also means that heaters can be used to control the temperature, allowing crops to be grown during winter. Nutrifungus grows on lichen-covered soil and must be planted and remain in complete darkness. It can be grown in any terrain that is sufficiently fertile to support a growing zone, including fungal gravel and hydroponics basins. Due to its low fertility sensitivity, it takes fewer penalties from poorer soils than other plants. However, it also benefits less from being in hydroponics. Nutrifungus is immune to blight.
Devilstrand Mushrooms are another type of mushroom that can be grown in Rimworld. They are fragile mushrooms that have been genetically engineered to produce silk nets of the highest grade. They can be unlocked by researching "Devilstrand". Devilstrand Mushrooms take a very long time to grow, and some do not recommend growing them.
To farm wild fungi slowly in a dark room inside a mountain, players can build a farm in an undermountain cavern and have it farmed by slaves in a closed, self-sustaining environment. The first generation may be difficult, but by the third generation, they will wander around in the dark, tending to the mushrooms.

Mods can allow players to grow cave plants directly
The Prison Labor mod is another option that allows players to set work priorities for prisoners, including cutting plants and harvesting crops. With this mod, players can utilize prisoner labor to grow plants in caves, although it may require additional mods for converting floors to dirt or using hydroponics with sun lamps.
Additionally, the Nutrifungus crop in Rimworld can be grown in complete darkness, making it ideal for indoor and cave farming. It grows on lichen-covered soil or fungal gravel, and its low fertility sensitivity means it can thrive in poorer soils. Nutrifungus is also immune to blight and is less susceptible to raiders setting it alight.
The Devilstrand Mushroom is another unique mushroom in Rimworld that can be grown. It is a fragile, genetically engineered mushroom that yields high-grade silk fibers when harvested. However, it takes a very long time to grow, and some players do not recommend it for that reason.
Players can also get creative with their mushroom farms by building them around steam vents or geysers to prevent infestations and save wood. Additionally, enclosing animals within the mushroom farm can provide a source of meat. These strategies showcase the versatility of cave plant growing and the potential for self-sustaining underground ecosystems in Rimworld.
