Introduction
This glossary provides definitions and explanations of terms commonly used in discussions about psychedelic mushrooms, microdosing, cultivation, and related topics. Understanding these terms will help you navigate the information on this site and engage more effectively with the psychedelic community.
Terms are organized alphabetically for easy reference. Each entry includes a clear definition and, where relevant, additional context or explanations.
A
5-HT2A Receptor
A subtype of serotonin receptor that is the primary target of psilocybin. Activation of this receptor is responsible for most psychedelic effects.
Abort
A mushroom that stops growing before reaching maturity. Aborts are often more potent by weight than fully mature mushrooms.
Agar
A gel-like substance used in mushroom cultivation for isolating clean cultures, storing cultures, and testing for contamination.
Annulus
A ring or veil remnant on the stem of some mushrooms, formed from the partial veil that covers the gills when young.
B
Bad Trip
A challenging, difficult, or frightening psychedelic experience. Many prefer terms like "difficult experience" or "challenging journey."
Baeocystin
A minor psychoactive alkaloid found in some psilocybin mushrooms, structurally similar to psilocybin.
Bluing
A reaction where mushroom flesh turns blue or bluish-green when bruised or damaged. This is a characteristic of many psilocybin-containing mushrooms.
Bulk Substrate
The main growing medium used in mushroom cultivation, typically a mixture of materials like coco coir, vermiculite, and nutrients.
C
Cap
The top part of a mushroom, also called the pileus. It protects the gills and contains spores.
Colonization
The process by which mycelium grows through and consumes substrate, turning it white as it spreads.
Contamination
Unwanted organisms (bacteria, mold, etc.) that infect mushroom cultures or grows, often causing failure.
Cubensis
Short for Psilocybe cubensis, one of the most commonly cultivated and consumed psilocybin mushrooms.
D
Default Mode Network (DMN)
A network of brain regions active during rest and self-referential thinking. Psilocybin reduces DMN activity, which may underlie therapeutic effects.
Dephosphorylation
The chemical process by which psilocybin is converted to psilocin in the body, removing a phosphate group.
Dosage
The amount of mushrooms or psilocybin consumed. Typically measured in grams of dried mushrooms or milligrams of psilocybin.
E
Ego Dissolution
A state experienced during psychedelic trips where the sense of self dissolves, often described as feeling one with everything.
End-of-Life Anxiety
Anxiety related to terminal illness and death. Research shows psilocybin can be particularly effective for this condition.
F
Fadiman Protocol
A popular microdosing protocol: one day on, two days off, developed by Dr. James Fadiman.
Field Capacity
The optimal moisture content of substrate—moist but not waterlogged. Tested by squeezing: should release a few drops, not a stream.
Fruiting
The process by which mushrooms grow and mature. Also called pinning when small mushrooms first appear.
G
Gills
The thin, blade-like structures under the cap that produce and hold spores. Also called lamellae.
Grain Spawn
Colonized grain used to inoculate bulk substrate. Common grains include rye, wheat, and millet.
G2G (Grain to Grain)
A technique for expanding spawn by transferring colonized grain to fresh grain.
H
Heroic Dose
A very high dose of psilocybin (typically 5g+ dried mushrooms), popularized by Terence McKenna. Requires extensive preparation.
HPPD
Hallucinogen Persisting Perception Disorder—rare condition where visual changes persist after psychedelic use.
Hygrophanous
A property of some mushroom caps where they change color significantly when wet vs. dry.
I
Integration
The process of processing, understanding, and applying insights from psychedelic experiences to daily life.
Inoculation
The process of introducing spores, mycelium, or liquid culture to sterile substrate.
L
Lemon Tek
A preparation method where ground mushrooms are soaked in lemon juice before consumption, producing faster onset and more intense effects.
Liquid Culture (LC)
Mycelium suspended in nutrient liquid, used for fast inoculation of spawn.
M
Macrodose
A full psychedelic dose (typically 1.5g+ dried mushrooms) that produces full psychedelic effects.
Microdose
A sub-perceptual dose (typically 0.1-0.5g dried mushrooms) that doesn't produce full psychedelic effects but may provide subtle benefits.
Mycelium
The vegetative part of the fungus, consisting of a network of thread-like hyphae. This is what colonizes substrate.
Mystical Experience
A profound experience characterized by unity, transcendence, sacredness, and profound meaning. Research suggests these experiences correlate with therapeutic benefits.
N
Neuroplasticity
The brain's ability to form new neural connections and reorganize itself. Psilocybin promotes neuroplasticity.
Nootropic
A substance that may enhance cognitive function. Some people consider microdosing a nootropic.
P
PF Tek
Psilocybe Fanaticus Technique—a beginner-friendly cultivation method using brown rice flour and vermiculite in jars.
Pharmacokinetics
The study of how drugs are absorbed, distributed, metabolized, and eliminated by the body.
Pin
A small, immature mushroom that has just begun to form. The stage before full fruiting.
Placebo Effect
Benefits experienced due to expectations rather than the substance itself. Research suggests placebo may play a role in microdosing effects.
Prodrug
A compound that must be converted in the body to become active. Psilocybin is a prodrug that converts to psilocin.
Psilocin
The active metabolite of psilocybin. It's what actually binds to serotonin receptors and produces effects.
Psilocybin
The primary psychoactive compound in psychedelic mushrooms. A prodrug that converts to psilocin in the body.
R
Rhizomorph
Thick, root-like strands of mycelium that help the fungus spread and absorb nutrients.
S
Serotonin
A neurotransmitter involved in mood, cognition, and perception. Psilocybin acts on serotonin receptors.
Set and Setting
Set refers to mindset and expectations. Setting refers to the physical and social environment. Both are crucial for safe, beneficial experiences.
Spore Print
A pattern made by allowing mushroom spores to fall onto paper. Used for identification and cultivation.
Spore Syringe
A syringe containing mushroom spores suspended in sterile water, used for inoculation.
Stamets Stack
A microdosing protocol combining psilocybin, Lion's Mane mushroom, and niacin, developed by Paul Stamets.
Stem (Stipe)
The stalk of a mushroom that supports the cap.
Still Air Box (SAB)
A plastic box with arm holes used for sterile work in mushroom cultivation.
T
Tolerance
Reduced sensitivity to psilocybin after recent use, requiring higher doses for the same effects. Develops quickly but resets within days.
Trip Sitter
A sober person who stays with someone during a psychedelic experience to provide safety and support.
Tryptamine
A class of compounds that includes psilocybin, psilocin, and serotonin. Structurally similar molecules.
V
Veil
A membrane that covers the gills of some mushrooms when young. The partial veil may leave an annulus on the stem.
W
Wavy Cap
Common name for Psilocybe cyanescens, known for its wavy cap margins and high potency.
