Mycology

Mushrooms have their own chain. Everything is kept abstract: game times and chances, no real-world cultivation parameters.

#The chain

1. Spore Print. Fresh mushrooms and paper craft into a print (4 uses).
2. Agar Plate. Glass panes, dried kelp and a water bottle make 2 plates. Holding the spore print in the main hand and a plate in the off hand, right-click a Still-Air Box to inoculate it. The plate colonises in about 5 minutes.
3. Grain Spawn Jar. A glass bottle and 2 wheat. A colonised plate (main hand) inoculates a jar (off hand) in the box; the plate is used up. The jar colonises in about 10 minutes.
4. Monotub. Fill it with Bulk Substrate (a coir brick from jungle logs, manure from plantations:manure (bone meal by default) and a water bottle), then add a colonised jar. The tub colonises in about 10 minutes.
5. Fruiting. Mist the colonised tub with a water bottle or the Watering Can. In dim light (11 or less) and a mild climate it fruits. Right-click to pick the flush. There are four flushes, each smaller than the last (6, 4, 3, 2 mushrooms), and the tub must be misted again before each. After the fourth the tub is spent and empty.

Cultures keep growing while the item sits in a chest: their progress follows the game clock. The tooltip shows the progress, and the item looks different once colonised or contaminated.

#Contamination

Every inoculation can mould. You only find out when colonisation is done:

Sterilise empty plates and jars in a Pressure Cooker over a lit campfire, fire, magma or lava. It takes about half a minute per stack. A contaminated tub is emptied with a right-click.

#Species

Each species has one way into cultivation, as in reality:

Species	Wild	Cultivation
Psilocybe cubensis	Swamps, mangroves, jungles (on grass, mud, podzol)	Spore print → plate → jar → Monotub (the easy one)
Psilocybe cyanescens	Taigas, dark forests	Spore print → plate → jar → Wood Chips bed outdoors
Psilocybe semilanceata (liberty caps)	Appear in the rain on pasture grass (plains, meadow) near cows and sheep	None: foraging only. Its spores give no print.

• Mushroom blocks grow in shade (light 12 or less). Break a mature one for 1–3 fresh mushrooms, or use paper on it for a spore print (cubensis, cyanescens).
• Wood Chips (a log makes 4): lay a bed and spawn it from a colonised cyanescens jar. The mycelium spreads through touching wood chips and fruits cyanescens on top in cool biomes (temperature 0.7 or less) in shade or rain; with Serene Seasons only from early autumn to early winter. A monotub refuses cyanescens, and wood chips refuse cubensis.
• Liberty caps: every 10 seconds, while it rains, one cow or sheep near each player has a 1 in wildRarity (default 3) chance to leave a few caps on open grass around it in a pasture biome (plantations:has_wild/psilocybe_semilanceata), at most 4 within 8 blocks. Late-game pasture inoculation is left for later.
• Products: fresh mushrooms dry on the Drying Rack; 2 dried mushrooms of any species and a water bottle brew Mushroom Tea. Effects come with the substance system.
• Config: plants.psilocybe_cubensis, psilocybe_cyanescens, psilocybe_semilanceata (enabled, wild, wildRarity).
