Wind-carried spores in Mycelarium are how you cross a gap that no hypha shot can reach. A surface mushroom releases drifting white spore particles that blow away from the colony, and a spore that lands seeds a new growth point you can grow from — so an obstacle too wide to shoot across becomes a place you can already expand into.
Mycelarium wind carried spores: where they come from
The spores come from above ground. A mushroom standing on the grass line with its hyphae running down into the soil drifts spore particles out into the forest, and the wind carries them away. That is why a colony that never builds on the surface cannot use this mechanic at all.
Where to put those mushrooms, and what else surface building gives you, is in building mushrooms on the surface.
There is a second source worth knowing: the hedgehog. If it picks up a Spore Mushroom you can shoot spores right from its back while it is running, so a colony with a hedgehog problem has a use for the animal it was fighting.
Which mushroom launches them
The Spore Mushroom is the node that unlocks them, and two upgrades decide how useful they are:
- Spore Count — how many spores are launched.
- Spore Quality — how well they carry, which leads to Spore Lightness.
All three sit in the FRUITING BODIES branch of the tree. The roles of the Spore Mushroom next to the other mutations are in the mushroom mutation list.
What happens when a spore lands
A landed spore seeds a new growth point, and you grow from that point exactly as you would from any other node — press and hold, drag, release. That means a spore is not just a shortcut across a gap; it is a new anchor for the network, and it is often the cheapest way past stone that no shot will ever cross.
