Below is a list of common terms used by mushroom growers. This list is a work in progress, so please be patient while we add new terms.
An Abort is a mushroom that stops growing at various stages in the growth cycle. Aborts will generally have a black or dark brown cap and will never reach maturity.
An agar plate is a petri dish with a growing medium comprised of Agar (a gelatinous substance) and some sort of sugar. Agar plates are used to grow fungus, molds, and other organisms.
The process of removing a fully colonized mycelium cake, such as a BRF cake, from its container.
Shorthand for brown rice flower powder. Used as food/nutritional source for growing mycelium.
The top section of a mushroom. Often conical shaped on top, with gills on the underside.
A non-nutritious layer of hydrated medium which covers the fully colonized cake. The casing layer is used to encourage fruit body production.
Cobweb is a mold contaminate that resembles cobwebs in appearance. It is often found growing on the top of the substrate or casing layer. Cobweb is a contaminate and is easily killed by spraying the mold with hydrogen peroxide.
A course fiber made from the husk of a coconut. Coco has antimicrobial properties and absorbs water very well making it an ideal material for mushroom substrates.
Found at pet supplies stores or on Amazon
Mycelium is a network of fungal threads, that form the vegititative body. The fruiting bodies, or fruits, such as mushrooms, can sprout from a mycelium.
When compared to a plant, mycelium is the root system and the mushroom is the flower.
Live mycelium in a liquid broth consisting of a sugar and water.
Material for the mycelium to grow in. Usually comprised of organic materials such as sawdust, manure, coco coir, vermiculite, grains, straw, and other matter.
introduction of mycelium culture or spores to the substrate. Innoculation is done to start the growth process.
Acronym for Traditional Ecological Knowledge. Although not identical in meaning, the use of “TEK” may be thought of as a technique. Often prefaced with the type of Tek; e.g. PF-Tek, Bucket Tek, Uncle Bens Tek, etc…
A type of green mold. Contamination. Starts out white, turns green when it begins to release mold spores. If you see green mold it is already too late.
Substrate material that is fully colonized by mycelium.
Microscopic reproductive organisms that are released by a mature mushroom. Think of spores as seeds.
A syringe containing a mixture of sterilized water and mushroom spores.
Mushrooms collected on a medium such as tin foil. Spore prints are made by removing the cap of the mushroom and placing over a collection medium.
Polyester fibers that resembles synthetic cotton. Used to control air-flow in monotub grow chambers. Can be purchased at craft and fabric stores or on Amazon.
A process of partial-sterilization whereby substrate is heated to 140-160F for a period of 1-8 hours. The goal of pasteurization is to kill off harmful microbes while keeping beneficial microbes alive.
