A B C D E F G H I L M N P R S T

Clarity First

We avoid jargon where possible and note when slang differs from scientific usage.

Safety Notes

Entries flag risks (e.g., dosing, interactions) and link to safety pages for deeper guidance.

Respect & Context

Cultural or ceremonial terms include reminders about appropriate context and consent.

A

Abort

Adnate

Gills that are broadly attached to the stem of a mushroom.

Afterglow

The period after a psychedelic experience characterized by positive mood, increased well-being, and enhanced appreciation for life. Can last hours to days after the primary effects subside.

Annulus

A ring-like structure on the stem of a mushroom, formed from the remnants of the partial veil.

Anxiety

A feeling of worry, nervousness, or unease. Can be increased or decreased by psychedelic experiences depending on set, setting, and individual factors.

B

Baeocystin

A psychoactive alkaloid found in some psilocybin-containing mushrooms. Less well-studied than psilocybin and psilocin.

Bad Trip

A difficult, frightening, or unpleasant psychedelic experience. Often characterized by anxiety, fear, confusion, or paranoia. Can be managed with proper set, setting, and support.

Bluing

Bulk Substrate

A nutrient-rich growing medium used in mushroom cultivation, typically consisting of materials like coir, vermiculite, and other organic matter.

C

Capsule

A method of consuming mushrooms by grinding them into powder and filling empty capsules. Popular for microdosing due to precise dosing and lack of taste.

Casing Layer

A thin layer of non-nutritive material (often coir or vermiculite) placed on top of colonized substrate to help maintain moisture and provide a microclimate for pinning.

Cluster Headaches

Severe headaches that occur in clusters. Psilocybin has shown promise in treating both abortive and preventive treatment of cluster headaches.

Colonization

The process by which mycelium grows through and consumes substrate material. Full colonization is required before mushrooms can fruit.

Come-up

The initial phase of a psychedelic experience as effects begin to manifest. Can be accompanied by anxiety, nausea, or physical discomfort for some users.

Contamination

Unwanted organisms (mold, bacteria, other fungi) that invade a mushroom cultivation setup. Can ruin a grow if not addressed.

Cracker-Dry

A term describing mushrooms that are completely dried, so dry that they snap easily like a cracker. Essential for proper storage and grinding.

Cubes

Slang term for Psilocybe cubensis, the most commonly cultivated psychedelic mushroom species.

D

Drying

The process of removing moisture from mushrooms, typically using a food dehydrator or air drying. Essential for long-term storage.

E

Ego Dissolution

The temporary loss or reduction of the sense of self during a psychedelic experience. Often associated with mystical or spiritual experiences.

Medical care for people with terminal illnesses. Psilocybin has shown promise in reducing anxiety and improving quality of life in end-of-life care.

F

Fadiman Protocol

A microdosing protocol developed by James Fadiman: one day on, two days off. One of the most popular microdosing schedules.

FAE (Fresh Air Exchange)

The introduction of fresh air into a mushroom growing environment. Essential for proper fruiting and preventing carbon dioxide buildup.

Field Capacity

The optimal moisture content of substrate material. At field capacity, substrate holds maximum water without being waterlogged.

Flush

Growing

The process of cultivating mushrooms, typically indoors using various techniques like PF Tek, monotub, or other methods.

H

Harm Reduction

Practical strategies and ideas aimed at reducing negative consequences associated with drug use. Emphasizes safety, education, and responsible use.

Heroic Dose

A term popularized by Terence McKenna, referring to very high doses (typically 5g+ dried) that produce extremely intense experiences.

Hyphae

Thread-like structures that make up the mycelium of a fungus. Hyphae grow through substrate, absorbing nutrients.

I

Identification

The process of correctly identifying mushroom species. Critical for safety when foraging, as misidentification can be dangerous or fatal.

Integration

The process of incorporating insights, experiences, and lessons from psychedelic experiences into daily life. Often considered as important as the experience itself.

Inoculation

The process of introducing spores or mycelium into a sterile substrate to begin the cultivation process.

L

Lemon Tek

A preparation method where mushrooms are soaked in lemon juice before consumption. Believed to convert psilocybin to psilocin more quickly, potentially leading to faster onset and more intense effects.

Lignicolous

Describes mushrooms that grow on wood. Many potent psilocybin species, like Psilocybe cyanescens, are lignicolous.

Lion's Mane

A medicinal mushroom often combined with psilocybin in the "Stamets Stack" microdosing protocol. Believed to enhance cognitive benefits.

M

Magic Mushroom

Common term for psilocybin-containing mushrooms, referring to their psychedelic effects.

Microdosing

The practice of taking very small, sub-perceptual doses of psychedelic substances, typically 1/10th to 1/20th of a full dose. Used for potential cognitive and mood benefits without significant psychedelic effects.

Monotub

A large plastic container used for bulk mushroom cultivation. The monotub method is popular for producing high yields.

Mycelium

The vegetative part of a fungus, consisting of a network of hyphae. Mycelium colonizes substrate before producing mushrooms.

Mystical Experience

N

Nausea

A common side effect during the come-up phase of psychedelic experiences. Can be reduced with preparation methods like tea or lemon tek.
