Most bought
Best-selling spore syringes & grow kits.
These are the products a lot of people go for, the Cylocybe Special MycoBox Grow Kit has sold so many we had to move to an industrial unit to cope with demand!
Microscopy Spores
Psilocybe cubensis spores.
We're all here for the same thing, to check these out under the microscope!
Every spore syringe is made clean with a state of the art ISO4 (better than ISO5) laminar flow hood and with sterile technique developed over 20 years.
And every Psilocybe cubensis is available in 12ml, 3ml and 1ml spore syringes, 12ml vials, spore swabs and foil spore prints.
Our microscopy spores are sold for legal microscopy research only. Our grow kits are strictly for culinary or medicinal cultivation. Never mix the two together.
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
We choose one of our favourites from everything that is in-stock (sometimes even a surprise variety that yet in the shop!). If you don't know what to go for, go for this.
Spore stock status.
We are currently awaiting an imminent restock for some of these! If you want reminding when something comes back in stock, go to the product page and click 'Tell me when it's back' and we'll drop you an email.
Psilocybe cubensis
Rare & exotic
Species like Psilocybe Cyanescens and more will be restocked in the coming days.
Spores
How spore syringes are produced and prepared.
From our flowhood
Preparing your syringes as clean as we possibly can.
To get an idea of the attention to detail which earned us the respect for actual quality, not the saying 'quality' and not really meaning it, well, it's about investing in the best equipment we can afford and having OCD levels of attention, it's where some of those traits like OCD or the hyperfocus ADHD gives you become your super powers! It's impossible to teach that, you have to want to provide the best for the customers who pay you hard-earned money:
After our syringes are filled with spore solution, they are immediately passed over to a second expert responsible for screwing on the sterile syringe caps, all whilst sitting in front of our ISO4 HFLT1800 laminar flow hood (10 times finer filtration than the industry standard ISO5).
The capped spore syringes are then quickly sealed in ziplock bags.
Once we finish filling and capping the spore syringes, we clean the stainless steel workspace. Then, one by one, we take each spore syringe and pack it into a laminar-foil, light-blocking bag. We never label within the lab because dirty, sticky labels don't mix well with latex-gloved hands and sitting a printer in front of a laminar flowhood would call for some life choice evaluation!
This all means the syringe itself will never be labelled, keeping it super clean. When the time comes to remove it from the foil bag, you won't cross-contaminate your workspace by handling a syringe with a dirty trich-ridden exterior.
Our labelling is performed on the laminar-foil bag after we exit the the laminar flow hood and lab and we strictly only use labels made from polypropylene so YOU can safely wipe the whole thing down with isopropyl alcohol before taking it into your SAB for that extra caution.
Our entire production process for spore syringes is carefully thought out and designed for the customer's benefit, not our own (and yet, our prices are still amongst the lowest in the UK).
Exotics & rare species
Rare & exotic magic mushroom spores.
We also carry many more species for the serious microscopy connoisseur, like Pan. cyanescens (MIB and TTBVI), Psilocybe azurescens (the flying saucer), Psilocybe cyanescens (the wavy cap), sclerotia / truffle spores like Psilocybe mexicana and P. tampanensis, and much more.
Please bear in mind that many of our exotic species are wild-foraged and printed, and so could have the odd hitchhiker, unlike our P. cubensis, which are legally lab-cultivated and printed for ultimate cleanliness.
Panaeolus cyanescens
TTBVI
The wild Caribbean Blue Meanie. A British Virgin Islands locality line of Panaeolus cyanescens with a tamarind-tree origin story and a big potency reputation. For spore microscopy only.
Out of stock
Psilocybe Cyanescens
The caramel wood-chip Psilocybe with the undulating cap margin and a purple-brown print, scientifically born in Britain at Kew. A landmark wood-loving species and a rewarding microscopy subject. Sold strictly as a spore specimen for microscopy, taxonomy and collecting.
Out of stock
Psilocybe Semilanceata
The wild British grassland icon and the conserved type species of the entire Psilocybe genus. A tiny sharp-nippled conical cap that you study, print and identify, never farm. Offered strictly as a microscopy and taxonomy reference specimen.
Out of stock
Sclerotia species
Magic truffle microscopy spores.
The mushroom species commonly known as 'magic truffles' are particularly extraordinary, due to their ability to form into both mushrooms or schlerotia stones dependant on the fruiting conditions. 600X magnification is what we recommend!

Psilocybe Mexicana
The mushroom modern psilocybin science actually began with. Roger Heim named it in 1957, grew it in his Paris lab, and from that cultivated material Albert Hofmann isolated the first pure psilocybin.
Psilocybe Tampanensis
The sclerotia-forming Psilocybe behind the "Philosopher's Stone": a sandy-meadow rarity from Florida, known to science from almost a single 1977 find, with small angular spores and a purple-brown print all its own.
Sterile and injectable
Mushroom grow kits,
made easy.
At Cylocybe, our mission (as corny as it sounds) is to make mushroom growing as common as house plants!
Nervous newbie? Don't be... Growing mushrooms is EASY. Our mushroom growing kits come with grow guides, plus we're here to help if you get confused about anything - just ask us.
As well as growing mighty mushrooms with success, you'll be fascinated with every step of the journey. From watching the mycelium take over the mushroom spawn, then into the substrate, to the tiny pinheads that form into big mushrooms, to the caps which stretch open to rain down spores... The full life cycle, from spore to spore. If that doesn't get you excited, you've picked the wrong hobby!
MycoBox Grow Kit
The original single-stage kit. You inject your own gourmet culture straight into the sterile substrate box through the ports on the lid, colonise, then dunk and fruit in the included tent. One box, no grain step.
MonoBox™ Grow Kit
Like a dialled-in 'Monotub' grow without the hassle! Give your mushrooms the humidity and airflow they deserve with our brand-new included Cylo Grow Tent.
PF-Tek MycoBox Grow Kit
Our original kit, the classic PF-Tek cake brought up to date. You inject one sterile brown-rice cake through a single port, let it colonise, then dunk and fruit it in the included tent. Hands-on, and the friendliest place to start.
PF-Tek MycoPots Grow Kit
The classic 1990s beginner method, three sterile cakes you inoculate yourself. Inject, colonise, dunk and roll, then fruit all three in the included tent.
Every product comes with simple instructions. On our busiest weeks, we can produce and dispatch up to 200 MycoBox and MonoBox™ grow kits... our guides have to be perfect.
We pioneered the injectable MycoBox design that's been copied across the industry. When you buy from Cylocybe, you're getting the genuine product.
Replacement cover, explained
EZ-Replace™
EZ-Replace™ is by far, the most generous thing we've ever brought to Cylocybe. Even more so than doing away with BS spore prices. Read below to see what we mean by that.
Spore syringes and vials
We already cover spore syringes for up to 4 weeks, but this requires you to explain what the issue is and will always be at our discretion whether we replace or not. EZ-Replace™ guarantees an easy replacement for up to 6 weeks, with no questions asked and a self-management portal to let you add the replacement straight to your basket.
Grow kits for gourmet
Without EZ-Replace™, a grow kit is covered before it has been used. Once you have started it we may still replace the main sterile component, but we will need photographs and it is always at our discretion. EZ-Replace™ guarantees an easy replacement for up to 12 weeks, used or not, with no questions asked and the same self-management portal.
We built this to be human. If you need a replacement, or if shit's tight, just take one.
Gourmet favourites
Grow gourmet mushrooms at home.
Our selection includes a wide range of delicious and easy-to-grow species, including shiitake, king oyster, and lion's mane. All of our cultures are lab-processed from certified mother cultures, ensuring the highest quality and success in your home mushroom cultivation efforts.
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.
Out of stock
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.
Out of stock
King Oyster
Live King Oyster mycelium suspended in a sterile nutrient broth, ready to inject into grain or agar. A faster, cleaner start than spores, from known genetics.

Spawn, substrates & supplies
Mushroom growing supplies.
Looking for Vermiculite, Perlite, Coco Coir, Brown Rice Flour or some other mushroom growing supply? We stock just about everything you can want in this hobby!
Vermiculite (10L)
Expanded mineral flake that soaks up water and lets it go slowly. The standard moisture buffer for PF Tek cakes, bulk coir mixes and casing layers.
Perlite (5L)
Expanded volcanic glass. Used wet as a humidity buffer in fruiting chambers, and dry as an airy amendment in substrate and casing mixes.
Coco Coir (650g)
A compressed block of coconut-fibre coir. Add boiling water and it breaks down into a clean, water-holding bulk substrate for fruiting mushrooms.
Brown Rice Flour
Organic wholegrain brown rice flour, the nutrient half of a classic PF Tek substrate. You mix it with vermiculite and water, sterilise it in jars, then grow from it.
SporeKit™ Testing Kit
Test your gourmet mushroom 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 gourmet mushroom spores before risking your substrate.
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 which we demonstrate in the photos below.
Perfect your sterile technique and grow cleaner flushes.

Newly stocked.
We're working hard to stock our shelves right now! If there's a particular mycology supply we don't have, chances are we have it so get in touch.
Sabla™ / Still-air Box (S/M/L/XL)
Lids with laser-cut arm-holes for 'Samla' 65L and 130L tubs from Ikea. We do not provide the tub, just the lids.
PF-Tek MycoPot Grow Kit (DIY)
The original cake method, the hands-on way. You make up and sterilise eight brown-rice cakes yourself, inoculate them with your own gourmet culture, then dunk, roll and fruit them. You finish it understanding every stage of a grow.
Peptone (10g)
A water-soluble protein powder that gives mushroom mycelium ready nitrogen and amino acids. A small amount enriches a litre of liquid culture or agar.
Glycerine (130ml)
Food grade glycerine for the lab. Its main job in mushroom work is as a cryoprotectant, so you can freeze mycelium and spores without ice damage killing them. Supplied in a 130mL bottle.
3% Hydrogen Peroxide (1L)
A 1 litre bottle of 3% hydrogen peroxide (10 volume) for spot-treating early cobweb mould and sanitising tools and work surfaces. It breaks down to water and oxygen and leaves no residue.
Light Malt Extract (LME 100g)
A food-grade dry powder made from malted barley. It is the standard sugar base for malt extract agar and malt extract liquid culture, the two media most home growers use to grow and keep clean mycelium.
Dextrose (100g)
Food-grade dextrose powder, the simple sugar mushroom mycelium feeds on. You add it to liquid culture and nutrient agar to give cultures a clean, fast carbon source.
Agar‑Agar Powder (50g)
A plant-based gelling powder from red seaweed. You add it to a nutrient like malt extract to set firm, clear plates for starting and cleaning up mushroom cultures.

What customers say.
Your experience makes a huge impact, personally and professionally. Fewer than 1% of customers leave a review, so your story is a powerful guide for other mycoscopy geeks and growers. That's why we don't ask for feedback straight away. We wait a couple of months to give you a proper chance to test our products. When you see that invitation email, we'd be massively grateful for your honest feedback.
This is my second order and it’s as perfect as my first one. If I had a criticism it would be I preferred the brownie I received with my first order as opposed to the cookies I received with my second, that’s how pleased I am with the service from you. Ps the cookies were nice though
I was blown away by extra snack bars in the box it hasn’t been 5 seconds and I’m chewing on it, the rest of the day was legendary due to that occurrence. But don’t expect it, it won’t be a surprise then. And after all maybe Its for higher value orders or I’m just special, but overall its a value packed easy peasy to understand package I love these people behind all this. It’s the easiest thing i could have gotten, life is easy.
I bought, I grew, I harvested, and I consumed. I waited for all four before leaving a review. I am a first time grower, hence I even dehydrated my culinary mushrooms on my radiator. I ended up with about 28 grams of culinary mushrooms after drying, and that was after throwing my brick out after 3 flushes, even though it could have handled at least one more - mainly because the mycelium was looking tired. My fault, I'm only new. Very happy with product. Better than I expected. Start to end-of-third-flush took 2.5 months.
Well packaged, and with absolutely no signs of contamination when viewed under a microscope. I imagine that if a hardened criminal were to cultivate them, by now the spores would be busily colonizing a spawning substrate with pure white mycelium.

Frequently asked questions
Spore and grow-kit basics.
Are your spore products legal to buy?
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.
What's the difference between spore syringes and liquid culture?
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.
What does ISO4 actually mean?
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.
How long does shipping take?
It comes in two parts: how quickly we dispatch, then how long the courier takes. Dispatch time varies by product and is shown on each product page (spores go out faster than made-to-order grow kits). Once dispatched, most UK orders arrive within 1-3 working days of dispatch depending on whether you pick Express or Economy, and worldwide delivery is typically 5-15 working days depending on the service you pick. Your exact dispatch date and delivery estimate are shown at checkout for your address before you pay.
Is shipping discreet?
Yes. Plain packaging, no branding, no give-away of contents.
What's the difference between MonoBox™ and MycoBox?
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.
Why do we always use ™ for product names?
Since we started in 2017, we've been copied rotten. When I say that, I mean it. From entire clones of our site, our copy, Ruth's illustration style, our killer innovations like glueless injection ported lids (yep, us!), my CVG+Coffee (aka Cylocybe Special grow kits), the components of a new gen commercial sterile grow kit (inc. perlite - us, inc. sterile gloves - us, inc - chlorhexidine wipes - us, inc. SacO2 bags as a fruiting tent - us) You get the idea. Our product copy, our HTML code (as well as the hilarious bug I couldn't fix on it). The only vendor to ever ask our permission to use a product idea was MushBuddies. The Morel of the story - if we put TM on a name, it's just a sign to the competitors who watch our site more than we watch theirs to give us a break. Sorry, that turned into a bit of a rant.
What if my spores look wrong under the microscope?
Optional cover you add in the basket. If a covered item lets you down, a like-for-like replacement drops into your basket for £0, no questions asked. We may still allow some replacements regardless, but this will be judged on a case-by-case.
What if you don't stock the strain I want?
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.
Please note; the following pictures show live agar culture being produced with the assistance of a laminar flow hood, you aaaabsolutely do not need one in this hobby to achieve 90-95% success rates - a cheap plastic Ikea tub with arm-holes cut in it will do you just fine (aka Still-air Box / SAB).
We now sell lids with laser-cut arm-holes so you can attach them to 'Samla' tubs from Ikea.
Warning fur wit yer 'bout tae see,
for a habitual nail biter are thee.
I'm intentionally doing the following procedure with bare hands to prove a point, that a 'risky' procedure can be done with without worry if you're a careful. Just ignore the £7K flowhood in the background and imagine I'm working inside plastic SAB!
(I really should have done this in a SAB, in retrospect...!)
