Cultivation – Another term for growing mushrooms, which can be done indoors or outdoors. Cultivation has four key phases: Inoculation, Colonization, Fruiting, Harvesting.
Colonization – When mycelium is growing, but no fruiting bodies (mushrooms) are present.
Culture – Mushroom mycelium of a particular species or strain, usually kept on a petri dish or slant.
Culturing – The act of isolating mushroom genetics into a culture.
Flush – A ‘crop’ of mushrooms. Mycelium tends to produce fruits in groups, followed by a brief resting period.
Force Fruiting – A process used to trigger the mycelium to produce fruiting bodies. Also called “shocking.”
Fruiting – The phase of growth in which visible mushrooms begin to appear on the substrate.
Fruiting chamber – An enclosed space mushroom growers often use to create an optimal growing environment.
Laying yard – The place where logs are incubated and routine maintenance is performed.
Inoculation – The process of introducing spores or spawn into a substrate.
Mycelium – The vegetative part of fungi that grows underground, consisting of fine white filaments.
Pins or pinning – When tiny fruiting bodies (the ‘baby mushrooms’) first begin to appear.
Spawn – The colonized carrier that holds a specific strain of mushroom mycelium until it is ready to transfer to another substrate.
Spawning – The act of adding mushroom spawn or spores to a media to kickstart the colonization process.
Spawn run – An incubation period after inoculation in which mycelium colonizes wood.
Spores – What mushrooms release into the air to reproduce. In the lab, you can use them to isolate specific mushroom genes and create a mycelium.
Strain – A specific variety within a mushroom species.
Substrate – Any material on which mushrooms can grow.
