Psilocybe cubensis
Golden Teacher
The mushroom that taught the hobby what a cubensis looks like. Wide golden-caramel caps, a heavy dark print, and a name everyone knows but nobody can quite source.

Psilocybe cubensis
B+
The big, easygoing classic, and the cube that taught half the hobby to focus a microscope. A heavy purple-black spore print and clean, textbook spores.

Psilocybe cubensis
Our Selection
Our house pick of Psilocybe cubensis: a dependable, classic-looking cube chosen for clean, heavy spore drops rather than a famous backstory. A curator's choice labelled.

Psilocybe cubensis
A+ Albino
The ghost-white cube that fooled its own name: a pale, blue-bruising leucistic line that still drops a proper dark purple print, so it studies like a classic A-strain and photographs like nothing else.
Shop A+ Albino →
Psilocybe cubensis
Amazonian
A big, old-school rainforest line carried out of the Amazon by a long-gone Hawaiian spore house. Tall fruitbodies and a dark, heavy, dependable purple-brown print made for the microscope.

Psilocybe cubensis
McKennaii
A European favourite named for Terence McKenna, famous for caps that go wavy and contorted at maturity. A plain cubensis with an uncertain backstory and a clean, dependable dark print.

Psilocybe cubensis
Cambodian
A wild Southeast Asian cube tied to the temples of Angkor Wat, with caramel-cinnamon caps and a dense, dependable purple-brown spore print that makes it a satisfying strain to put under glass.

Psilocybe cubensis
Z-Strain
The workhorse cube: a fast, aggressive colonising line famous for dropping heavy, dark prints almost as soon as the gills ripen. A reliable first strain to put under glass.
Shop Z-Strain →
Psilocybe cubensis
Mazatapec
An old Mexican-named line carrying the romance of the Sierra Mazateca, with caramel caps and a heavy, dependable dark purple-brown print that drops in mass.
Shop Mazatapec →
Psilocybe cubensis
Hawaiian
An old-school spore-vendor classic from the High Times era: caramel caps, a thick white stem and a generous, dark print that made it a staple of microscopy shelves long before "strains" were a marketing word.

Psilocybe cubensis
Jedi Mind Fuck
A big, chestnut-capped cube with a Star Wars name and a backstory nobody can pin down. Heavy, dense spore drops make it a generous strain to put under glass.

Exotics & rare species
Beyond cubensis:
the rare list.
Wood-lovers, Panaeolus and the UK's own liberty cap: a shortlist for the serious collection, in syringes, spore swabs and foil prints, with formats varying by species. Some are taken from wild outdoor specimens and can carry the odd "hitchhiker"; each product page tells you exactly what you are getting. Hover a name to see the specimen.

Legal for microscopy
Psilocybe spores are legal to own and study in the UK because they carry no psilocybin. We sell them strictly for microscopy and collection, never for cultivation. The UK law, in plain English →

Foolproof gourmet cultivation, built around the injectable MycoBox we pioneered. Inject, wait, harvest.
Everything for cultivation: the collections
Mushroom grow kits
The easiest way to grow.
The result of years of refinement. We've taken the guesswork out of gourmet mushroom cultivation, creating a foolproof system that works for everyone. We pioneered the injectable MycoBox design that's been copied across the industry, then built around it.
MonoBox™
Our most popular kit, and the one that teaches the real method. You inoculate the grain yourself, run it through sterile coir, and fruit a proper harvest in the included tent.
Shop MonoBox™ →
MycMonster™ XL
Our big, fast all-in-one bag. You inject a single 2L bag of Substrate B with your own gourmet culture and fruit in the same bag. Full colonisation in as little as 10 days.
Shop MycMonster™ XL →
CyLab™
A still-air box, a temperature-controlled incubator and a heated fruiting chamber, built into one compact, low-power system. It lets you grow gourmet mushrooms in any season, even through a cold UK winter, without heating the whole house.
Shop CyLab™ →
SporeKit™ Testing Kit
Test your spores
before risking your grow.
Gourmet spore syringe producers can't test every syringe they sell. If they claim otherwise, they're full of it. A few pounds for a SporeKit gives you the means to verify your own spores before risking a substrate block.
Choose between Grain (for syringes) or Agar (for swabs). And here's the clever bit: successful tests double as live culture syringes. The mycelium that grows out from a clean test can be injected directly into a grow kit, no re-pulling needed.
Perfect your sterile technique and grow cleaner flushes. Shop SporeKit →
Live mycelium in nutrient broth, ready to inoculate. Faster, cleaner pulls than starting from spore.

Lion's Mane
Live Hericium erinaceus mycelium suspended in sterile nutrient broth, ready to inject into your own sterilised grain to start a colonised batch.

Pink Oyster
Live Pleurotus djamor mycelium suspended in sterile nutrient broth, ready to inject into grain. A fast, warm-loving oyster strain that suits a first grow.

“The guides are very well made and the grow kits are made so that you actually understand each stage of the growing process and learn how mycelium actually works. It can take you from 0 to an experienced and knowledgeable grower.”

Frequently asked questions
The basics.
Yes. In the UK it is legal to possess and sell Psilocybe mushroom spores for the purpose of microscopy and collection, because the spores themselves contain no psilocybin or psilocin. Germinating and cultivating them is illegal and not what we sell them for. All our magic-species products are sold strictly for research, microscopy, and collection.
A spore syringe contains dormant spores in sterile water, intended for microscopy. A liquid culture contains live, actively growing mycelium in a nutrient broth, used for cultivating legal gourmet species and giving you faster, more reliable colonisation than starting from spore.
It's the cleanliness classification of our laminar flow hood. ISO4 is one tier stricter than ISO5, with fewer than 10,000 particles ≥0.1 µm per cubic metre of air. Every syringe is pulled under that hood, every time.
The checkout will calculate this for you based on dispatch days and shipping time.
Yes. Plain packaging, no branding, no give-away of contents. Tracked Royal Mail UK-wide. Free postage over £25.
MonoBox is the simple all-in-one (just inject and wait), our customer favourite. MycoBox is the original injectable design we pioneered. MycMonster™ XL is the brand-new oversized variant for big yields. All three accept the same syringes.
If you're spending hours on a substrate block, the ten-minute sterility test is worth it. The Agar variant goes further: successful test plates can directly inoculate a grow kit, no re-pulling needed.
We guarantee our spores are viable and clean for microscopy purposes. If you see anything unexpected, contact us within 6 weeks of dispatch with your order number and we'll replace the syringe.
If there are any magic spores we don't have, let us know and we'll put an order in. Our catalogue is driven by what customers actually ask for. Drop a request and we'll source it.
