• Setup
  • • Randomly choose a 1st player and give them the 1st player marker.
    • Create supply piles of resources.
    • Shuffle the mushroom tiles and place them in face down stacks.
    • Place the 2 starting much mushroom tiles in the center of the table:
      • Center (C): Earthlover
      • North (N): Pacific Gold Chantrelle
      • East (E): Fly Agaric
      • West (W): Painted Suillus
      • South (S): Common Deceiver
    • Place 1 carbon (black disc) on each of the 4 outer mushrooms.
    • Each player takes:
      • 1 player board in a color
      • 6 seedling tokens in the matching color
      • 18 root tokens in the matching color
      • 4 tree tokens in the matching color
      • 4 carbon (C) (black) onto the matching spot on their board
      • 2 nitrogen (N) (blue) onto the matching spot on their board
      • 2 phosphorus (P) (orange) onto the matching spot on their board
      • 2 potassium (K) (purple) onto the matching spot on their board
      • 3 mushroom tiles from the supply, this is their starting hand
    • Each player puts 4 matching tokens color side up (ready) on the top of their board.
    • Place the carbon track board off to the side of the play area.
    • Shuffle the bonus tiles and place the following number of tiles facedown on each square:
      • 2-3 players: 3 tiles per square
      • 4 players: 4 tiles per square
      • All unused tiles are removed from the game
    • Place each player's carbon track disc in the starting location at the bottom of the carbon board.
    • Shuffle the double-sided goal cards, flipping half the deck over between shuffles, and deal 3 next to the carbon board.
    • Place each player's goal track discs on the zero space of each goal card.
    • In turn order, each player chooses a position for their 1st seedling:
      • Place 1 seedling on a corner of the center tile and 1 root pointing at 1 of the starting mushrooms.
      • In a 2-3 player game, place seedlings from an unused player color on the remaining corners.
• Gameplay

  • Players take turns performing actions on their turn until a player reaches the end of the carbon track, which triggers the end of the game.

    Turns

    1. Perform 1 action. You can only take 1 action per turn.
    2. If you absorbed 1 or more carbon, move up 1 space on the carbon track.
    3. If you made any progress on a goal card, mark it with your goal counters on the goal card.
    4. Draw back up to 3 mushroom tiles in hand.

    Activation Tokens

    • You have 1 activation token per mushroom type.
    • When these are spent, they are flipped from their ready (color) to the used side (gray). Only ready tokens can be used.
    • These tokens are used to pay activation costs and/or absorb carbon.

    Carbon Track

    • You only move 1 stone on the track, regardless of how much carbon was absorbed on your turn.
    • Immediately take the benefit from the stone you land on.
      • For bonus tiles, look at all the tiles, take 1, and put the rest back face down.
        • Keep your tile face down. It may be discarded at any time for the benefit shown on it.
        • If the tile gives you points, reveal it during scoring at the end of the game.
    • When a player moves past stone 8, they place their token on 1 of the 5 round spaces and take the reward.
      • This triggers the end of the game.

    Placing Mushrooms

    • This only happens when you take the reproduce or partner action.
    • The mushroom tile must be placed orthogonally adjacent to at least 1 other mushroom.
    • Do not pay the cost shown on the mushroom (this is an activation cost).
    • When placing your seedling and/or root during the reproduce or partner action, you may place them on this new mushroom.
    • You may only place 1 mushroom on your turn (unless an ability allows you to do otherwise).
  • Action: Activate
    • • Activate a mushroom by paying its cost and activating its ability.
        • You must have a root on the tile you wish to activate.
        • Costs may include flipping over a ready activation token to its used side.
        • Carbon is payed onto the mushroom tile you are activating.
        • Some costs include P/N/K (Phosphorous/Nitrogen/Potassium) that is payed to the supply.
      • Mushrooms with "ONGOING" abilities do not need to be activated, they just boost other actions.
        • You must have at least 1 root on these mushrooms to use their abilities. Additional roots do not boost the abilities.
  • Action: Absorb
    • • Either flip any ready activation token or pay 1 cube of your choice to activate this.
      • Optional: You may move 1 carbon that you plan to absorb.
        • For each space you wish to move a carbon, either flip any ready activation token or pay 1 cube of your choice.
        • Carbon movements are only orthogonal.
        • You do not need to have a root on the mushroom where you are moving the carbon from.
        • You must have a root on the tile that you move the carbon to.
        • If you have a mushroom power that allows you to absorb 2 carbon, you may move 2 different carbon tokens, paying the costs for all of their movements separately.
      • Take 1 carbon off of a mushroom where you have a root and place it on your seedling.
        • You cannot pay extra to absorb more than 1 carbon.
        • Some mushroom powers allow you to absorb more than 1 carbon.
        • If your seedling has 3 carbon on it, return the 3 carbon to the supply and place 1 of your trees on your seedling.
          • You can only make 4 trees during the game.
          • If you have all 4 trees out, your seedlings can continue to absorb carbon, even beyond the limit of 3.
          • You do not get that seedling back.
  • Action: Reproduce
    • • Pay 1 carbon and 2 P to the supply to activate this.
      • Optional: You may pay any 1 cube to the supply to place 1 mushroom tile from your hand into the forest.
      • Place 1 seedling with 1 root on any unclaimed corner in the forest.
        • Once played, seedlings never move.
        • You don't have to place your seedlings near your other seedlings.
        • No other player may use that same corner.
        • The root must be touching the seedling you just placed.
  • Action: Partner
    • • Pay 1 carbon and 2 K to the supply.
      • Optional: You may pay any 1 cube to the supply to place 1 mushroom tile from your hand.
      • Place 2 roots onto mushrooms.
        • Each root must be attached to 1 of your seedlings.
          • Both roots may be attached to the same seedling, but it is not required.
        • You cannot place a root on a corner without a mushroom.
        • You can only place 18 roots during a game.
  • Action: Photosynthesize

    • This action is used to replenish your carbon and tokens.

      • Take 2 carbon from the supply.
      • You may pay any number of N to the supply to take an equal number of additional carbon.
      • Flip all of your used activation tokens to their ready side.
      • Optional: You may discard any number of mushroom tiles from your hand. Remember that you will draw back up to 3 mushroom tiles at the end of your turn.
• End of the Game

  • The end of the game is triggered when any player reaches the top of the carbon track. When this happens:

    1. Finish the current round (equal turns).
    2. Play 1 final round.

    Scoring

    • Goal cards are scored as indicated on the cards.
    • Score roots:
      • Seedlings with 1 carbon score 1 root.
      • Seedlings with 2 carbon score 2 root.
      • Trees score all their roots.
      • If you have more roots than carbon, you choose which root(s) to score.
      • The score of a root is the point value shown at the bottom of the mushroom tile.
    • Score any points printed on bonus tiles.
    • Gain 1 point for every 2 unused resources (C/N/P/K).
    • If you claimed 2 points at the end of the carbon track, score that.
• Goal Cards
  • • All players may score points on all 3 goal cards.
    • Some goals must be tracked during the game because they track when do something. Others track how much of a thing you have at the end of the game.
    • Some goals can go above 10. If this happens, leave your tracking disc on 10 and use your extra tracking disc to continue counting.
    • There are 3 different types of scoring tables:
      • Counter tables award points depending on where you are on the card's track.
      • Competitive tables award points depending on how you finished compared to the other players.
        • If there is a tie, add the point values for the tied places together and divide by the number of players, rounded down.
      • Multiplier tables award points by multiplying your position on the card's track or other variables.
  • Glossary
    • • 1A: Track how many times you made 6 or more carbon in a turn. You generally have to pay 4 or more N to do this. You can count carbon from bonus tiles or ongoing abilities.
      • 1B: Each time you Photosynthesize and pay N to gain carbon, move your disc up the goal track 1 space for each N paid.
      • 2A: You want to spread horizontally to have as many trees/seedlings as possible on vertical lines.
      • 2B: Count the number of unique mushrooms your trees/seedlings are touching. Each mushroom only counts once.
        • You do not need a root on a mushroom for it to count.
      • 3A: Count the number of trees you've grown.
      • 3B: Count how many seedlings/trees you have with 2 or more roots.
      • 4A: This tracks how many times you place 2 roots on the same type (symbol to the left of its name) of mushroom in a single turn. They may be on the same mushroom or 2 different mushrooms.
      • 4B: Count how many roots you've placed.
      • 5A and 5B: These look at the point value of the mushroom that each root is on and whether the value is even or odd.
        • A player may count a mushroom with multiple roots more than once as the count is by root.
        • Mushrooms with variable points are only counted by their point value at the end of the game.
      • 6A and 6B: These goals look at the name of the mushroom that each root is on. Mushrooms are marked with stars for names with a color and circles for names with a person/animal.
        • A player may count a mushroom with multiple roots more than once as the count is by root.
      • 7A: Each root can only count towards 1 set.
        • Mushrooms with variable points are only counted by their point value at the end of the game.
      • 7B: This goal counts how many seedlings/trees you have on the 12 corners created as a square with the Earthlover mushroom in the middle.
      • 8A: Move your disc up the track any time you take the absorb action or activate a mushroom that allows you to absorb and move 1 carbon 2 or more spaces.
        • If you move a different carbon 2 or more space in the same turn, you move your disc an additional space on the track.
      • 8B: This goal counts any time you ready all 4 activation tokens in a turn by any method.
        • Only used tokens can be readied, so you must have all 4 tokens in a used state to ready them all in a single turn.
