Mushroom Growing Terminology

Mycelium

The vegetative part of a fungus, consisting of a network of fine white threads (hyphae) that grow through the substrate and absorb nutrients.

Substrate

The material on which mushrooms grow. Common substrates include straw, sawdust, wood chips, coffee grounds, and agricultural waste.

Spawn

Mushroom "seed" - substrate (usually grain) that has been colonized with mycelium, used to inoculate larger growing substrates.

Inoculation

The process of introducing mushroom spawn or spores into a sterile substrate to start colonization.

Colonization

The period when mycelium spreads throughout the substrate, typically taking 2-4 weeks depending on species and conditions.

Pinning

The initial stage of mushroom formation when tiny "pins" (baby mushrooms) begin to form on the colonized substrate.

Fruiting Body

The mushroom itself - the reproductive structure that emerges from the mycelium to produce and spread spores.

Flush

A wave or crop of mushrooms that fruit at the same time. Most substrates produce multiple flushes over several weeks.

Cap

The top, umbrella-like part of the mushroom that protects the gills or pores where spores are produced.

Gills

The thin, blade-like structures under the cap where spores develop and are released (seen in oyster and shiitake mushrooms).

Spores

Microscopic reproductive cells released by mature mushrooms, similar to seeds in plants.

Sterile Technique

Methods used to prevent contamination by unwanted bacteria or mold during inoculation and early growth stages.

Humidity

Moisture level in the air, critical for mushroom growth. Most gourmet mushrooms require 80-95% humidity for fruiting.

FAE (Fresh Air Exchange)

The amount of fresh air circulating in the growing environment, important for proper mushroom development and CO2 reduction.

Contamination

Unwanted growth of mold, bacteria, or other fungi that competes with mushroom mycelium, often appearing green, black, or slimy.

Pasteurization

Heat treatment of substrate (usually 160-180°F) to kill competing organisms while preserving beneficial microbes.
