The UK's longest running magic spore specialist, born in 2017.
- Spore products go out same day when ordered and paid for before 1PM, grow kits same or next day.
- No annoying prices ending in 99p. Just clean, viable spores from the worlds best cultivation labs.
- Discreet post: plain packaging, nothing on the outside gives away the contents.
- Spores are sold for microscopy, taxonomy and collecting only - legal to own in the UK.
- Thousands of customer reviews - read the lot, stinkers included.
After our long hiatus, we're back to colonise this scene with the best mushroom grow kits we can make and a massive choice of magic mushroom spores for your mycoscope.
When you speak to us, you'll be speaking with a human being who sees you as the same, not a bot or someone who would have been better off having a bot speak for them.
We provide magical products for the soul* (*spores for microscopy research). And it's hard putting a price on that, but if I'm being pushed, it's Β£6 for a 3ml and Β£12 for a 12ml in case you are wondering.
Lots more products are in stock. More kits and spores coming imminently. We're behind on a few orders, so we'll be coming in on our day off tomorrow (Friday) to get those out with extra freebies as an apology or a postal upgrade to make up the delay. Cylocybe.com

These are the products a lot of people go for, the list should contain the MycoBox Grow Kit but it lost all of it's sales data... That kit has sold so many we had to move into an industrial unit (the list is dynamically generated).
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 P. cubensis is available in 12ml/3ml/1ml syringes, 12ml vials, swabs and foil spore prints.
Our microscopy spores are intended for legal study only. If you are up to mischief, we can't do business with you as that would be illegal! Got it?! π
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.
Price range: £3.00 through £20.00
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.
Price range: £3.00 through £20.00
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.
Price range: £3.00 through £20.00
Psilocybe cubensis varieties stock status.
We are currently awaiting an iminent 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.
Spores
Spore syringe production 101.
To get an idea of the attention to detail which kept us UK No. 1 year-after-year until our hiatus from the scene in 2023:
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 an ISO4 laminar flow hood (10 times cleaner than the ISO5 flowhoods our competitors use (ouch!) - but probably 10 times more expensive (OUCH).
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).
From our YouTube
Preparing a Cylocybe syringe.
Our syringes are fitted with professional tamper-evident luer-locking syringe caps which you may not have seen before (unless you've dealt with a vendor worth their salt). We use these so you know no-one has tampered with them between our lab and your hands.
Here's a quick video we made to show how they are used, notice the way we open a needle (for us, that's faster, cleaner and more practical) - open it how you want!
Playing it here streams from YouTube, they then see you're on our site. Click "Watch on YouTube" if you don't want that.
Not demo'd in the video: The plastic break-off component doubles as a screwdriver so you can remove the red cap without getting your grubby fingers anywhere near the exposed syringe opening!
Featured: the CubeΒ³ Special
Three syringes.
One cube.
Our three-in-one bundle: 3 Γ 12 mL Psilocybe cubensis spore syringes, each packed with viable, lab-clean genetics, your pick of strains. The cleanest cubensis spores in the UK, in one box, at a price that beats buying them apart.
Exotics & rare species
Beyond cubensis:
EXOTICS.
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.

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.
Price range: £15.00 through £30.00
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.
Price range: £20.00 through £30.00
Out of stock
Rare & exotic varieties stock status.
Species like Psilocybe Cyanescens and more will be restocked in the coming days. 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.
Sclerotia species
Magic truffles.
Sclerotia / truffle spores like Psilocybe mexicana and P. tampanensis.
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.
Price range: £15.00 through £30.00
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.
Price range: £15.00 through £30.00
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!

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!
All the more dangerous products, like the 15% hypo, Sodium Hydroxide etc will only be for Bank Transfer orders and will block crypto or cash in post at the checkout - this is us being a bit overly cautionary (sorry!).

SporeKitβ’ 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 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.
Perfect your sterile technique and grow cleaner flushes. Shop SporeKit β
Agar (for gourmet spore swabs)
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.

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.
Unfortunately we lost thousands of reviews which dated back to the beginning days of Cylocybe, after Trustpilot cancelled us for being a "bad-fit" for them in 2021. We blogged about it. If anyone can recover those reviews in full somehow, we’ll send you an All American 41.5 Quart Electric Steriliser (like we did for the 2000th Trustpilot reviewer!).
This is my second order and itβs 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, thatβs how pleased I am with the service from you. Ps the cookies were nice though
I have an issue with my order by t instead of help or a refund the guy started an argument with me what a c**t
I was blown away by extra snack bars in the box it hasnβt been 5 seconds and Iβm chewing on it, the rest of the day was legendary due to that occurrence. But donβt expect it, it wonβt be a surprise then. And after all maybe Its for higher value orders or Iβm just special, but overall its a value packed easy peasy to understand package I love these people behind all this. Itβs 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.

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...!)
