FAQ - Frequently Asked Questions

Please take 2 minutes to read this FAQ. Due to an overwhelming amount of emails of customers asking all these questions answered here we are now just referring customers back to this FAQ.

Can Psilocybe mushroom spores give you a buzz?

NO. Psilocybe mushroom (magic mushrooms) spores do NOT contain the scheduled drug psilocybin or psilocin. This is why they are legal. This was proven by a forensic scientific study by the FBI. You can read about it here.

Can I pick up an order? Do you have a store front?

No. Everything is done by mail order only, thank you for understanding. 

Are you still shipping during the corona virus pandemic? 

Yes we are still shipping but we are dropping off orders at night now when the post office is empty. They are stored indoors in the cool A/C. Other then that it's business as usual around here. 

An Item shows 1 in stock, do you only have 1 left?

No. We limit the quantity of that particular spore product per customer. We have an high demand for our spores right now and we want to spread the spore love around to as many people as possible. These low stock numbers usually means it might go out of stock soon though. We will increase the quantity numbers when supply catches up with demand. We are making them as fast as we can but their is a 2 week testing process that has to be done first. We welcome large variety orders, just not large orders of one particular strain.

Do you take preorders for out of stock spores?

No. You can't check out with out of stock items. There is an email notification system for out of stock items.

Can I pay with debit or credit card?

Yes and no. We can not accept cards directly as visa and mc won't allow the sale of psilocybe mushroom spores with cards. So we have alternative payment methods listed at checkout. You can use your debit card to pay through some 3rd party services we have listed at check out. Or to buy Bitcoin with your debit cards and pay us in bitcoin. Cash App is easy to use to buy bitcoin with a debit card as is Bitcoin.com. CashApp is actually cheap on fees for buying bitcoin, a lot cheaper than the exchanges. We also accept Apple Cash, which you use your debit card to buy through your Apple devices. We have lots of alternative payment methods listed at check out. We can not use other alternative payment methods such as PayPal, Venmo so there is no point emailing us to ask. Thanks for understanding. If you go through the check out process and start an order, all of the payment methods are listed in great detail. There is no harm in generating an order. If you want to change payment methods just make a new order please as there is no need to email us.

I sent you a payment how will I know when you received it? 

The simple answer is we send you an email with your tracking # that it was shipped. There is no automated response of when we receive your payments since we have to manually check them and change the order over to paid so it will ship out. You will usually get that email tracking # within 0 to 4 business days for digital payments. Mail orders take longer. We don't work weekends or holidays so take that into consideration. Further details are in your confirmation email that was sent to you right after you generated the order. Please don't email us asking if we received your payment. We are overwhelmed with these emails and it slows down your order and everyone else's orders. Unless it's been at least 2 weeks and you haven't heard from us, that usually indicates a payment problem.

Paying in Bitcoin (BTC)

Mushrooms.com is now giving a $20 to $80 discount when you pay in Bitcoin (BTC) More details of this can be found in our SPECIALS section here. 


At checkout, we have a bitcoin app that shows you the amount and payment address and QR code to scan with your bitcoin mobile wallet. When sending bitcoin, it's important to send the full amount on the order, in addition to the miners fees the blockchain charges for sending the transaction or any fees the exchange charges you. The easiest way to ensure you send the correct amount is to scan the QR code on mushrooms.com with your bitcoin mobile wallet. If you scan the QR code most wallets always send the correct amount. But some wallets do not, even the popular Coinbase wallet. Double check to make sure the amount sent is higher thann what is shown on your order. There are some wallets that will deduct the miner fees from the total of your order so you end up sending a shorted amount, then your order never gets changed to paid.  For example if your order total is 0.0004 you should see a higher amount being sent of .000444 which would include the minor fees. If the total being deducted from your wallet is exactly .0004 then the miner fees are not being calculated and your order will be short. 

If you send a shorted amount that is due on your order, this will cause our bitcoin app to NOT mark your order as paid and it will just sit there until you contact us asking questions about it. 

We have no idea who BTC is sent from unless the full amount is paid according to what is on your order. If you send a shorted amount, you can send the remaining amount to the same BTC address and it will change over to paid if done soon after. If it sits too long it will not work unless extra is sent because the price of bitcoin fluctuates a lot. Otherwise you will need to email us the exact details of the exact amount of BTC you sent and the dates. Sending screenshots of the exact btc amounts, date, and wallet sent to and from is all necessary data for us to find your transaction.  Then we can manually put the pieces of the puzzle together.  The easiest way instead of screenshots is to send just us the link to your transaction. Most wallets have a link that goes to blockchain explorer, explorer, block cypher, that allows us to input the address and or TX number to see the details of the transaction. All wallets and exchanges have this, usually in the form of a link at the bottom of the screen. Here is an example. 

Please note this is a big waste of time so please send the correct amount of BTC that is shown due on your order. Any minor fees your wallet charges you needs to be added above and beyond what is due on the mushroom spore order.

When Bitcoin is sent correctly, our app will email you a notification that your payment is complete after a few confirmation on the blockchain. This happens about 1 to 2 hours after sent, as the blockchain confirms the transactions. 

One more important caveat to note. If you need to wait on getting bitcoin, then make a new order when you get BTC in your wallet. BTC fluctuates a lot in price. If a few days later BTC goes up then your order will also be short. It's best to start over and make a new order. Otherwise this will also cause a shortage. Bitcoin goes up in value 10 fold every 2 years. It's a wise to buy extra bitcoin so you have enough to cover your order and fees and some left over to make you money!

How to Buy Bitcoin? Cash App makes it rather quick and easy to buy bitcoin with debit cards and bank accounts. But to send it you do have to upload an ID and get verified, this all happens quickly. Cash App's fees are very reasonable compared to exchanges. Bitcoin.com allows you to buy with a credit card. Localbitcoin.com connects you to meet locals and buy with cash. There is also bitcoin ATM machines in random locations throughout the world. There is a lot of bitcoin ATM's throughout the USA. Check this Paxful bitcoin ATM finder. Paxful.com also makes it easy to link buyers and sellers of bitcoin and pay in over 300 payment methods. Paxful makes it easy to buy bitcoin anonymously by using payment methods such as gift cards. CoinATMRadar.com also shows you bitcoin ATM's in your area. If you can find a CoinFlip ATM in your area, they charge low fees of 7%. 

Tips about sending bitcoin. Currently bitcoins value is going up fast. It's value multiplies 10X every 2 years! Big financial institutions, PayPal, Cash App, Greyscale and many more are all buying up bitcoin quickly, faster than it can be mined. Due to the high demand for bitcoin fees are higher than usual right now. One way to offset this is to send bitcoin at night and weekends when the bitcoin network is less congested. Saturday and Sunday is always the cheapest time to send.  


We are wasting an hour a day dealing with bad addresses that customers input. This is slowing down everyones orders. It's not fair to those who do input their address correctly. We will now only be dealing with bad address orders once per week. If you forget to include your apt. # or give a bad address, count on your order being delayed. PLEASE take time and read over your address carefully and input it correctly before sending the order. 

How long will spores last. What is their shelf life?

Mushroom spores can last for years!  For long term storage it’s best if spores are stored in the refrigerator. Spore prints need to be sealed from moisture before storing in the fridge. Sealing them from air and heat prolongs their life. Spore prints have been known to last 18 years! Perhaps longer but this is the longest we are aware of from our customer feedback and our network. Spore syringes do not last as long because eventually the water develops bacteria. A general guideline is 8 to 12 months. Although we have heard many reports of 2 to 5 years. If your spore prints do not germinate within the usual time frame then rehydrate them in sterile water for 24 hours. Spores prints older then 6 months should always be soaked in sterile water for 24 hours before attempting to germinate them. Liquid culture syringes should be used within 1 month of receiving them, especially in the summer months. Liquid culture syringes absolutely should be stored in the refrigerator unless they will be used soon. Except the Pink Oyster cultures, they should be stored at room temperature. We offer a 45 day viable guarantee on liquid culture syringes. We do offer a 60 day viable guarantee on spore prints and spore syringes. Most vendors in this industry offer 30 days or no guarantee at all on spores so we feel 60 days is plenty of time to know if there is any problems. Spore prints should not be stored in the refrigerator unless sealed from moisture, such as vacuum sealing. Liquid cultures should be stored in the refrigerator except the Pink Oyster Mushroom Cultures. Pink Oysters are tropical and do better at room temp. 

Our policy on spore syringes and bacteria, dead spores and replacements.  Spore syringes really aren’t good for using agar. Some times they will show bacteria on agar, yet when you put them directly to grain there is no signs of bacteria. On agar, the mushroom mycelium can not compete against the trace amounts of bacteria. But once put directly to grain, the mycelium easily outcompetes the trace amounts of bacteria and grows on the healthy mycelium. We learned this from Paul Stamets, one of the greatest mycologist of our generation. Because of this we don’t recommend using spore syringes on agar, unless you happen to be using gentamicin sulfate antibiotic powder. We use gentamicin in our agar for testing spore syringes. So our test batches will not show bacteria. Yours might show bacteria on agar if you’re not using gentamicin. Gentamicin is hard to find but you can find it at here at ShroomSupply.com. If you want to use agar for strain isolation etc.. or making liquid cultures, then we recommend using spore prints. You should also be aware that using too much spore solution on agar will cause bacteria. Only a few drops is needed. If you still want to use spore syringes on agar, then use gentamicin for best results. 

About 1 in 100 spore prints will naturally have trace amounts of bacteria. Once we combine many spore prints in our batch spore solution, this could cause trace amounts of bacteria in some batches of spore solution. 
Because of this we will not replace spore syringes from customers claiming to see bacteria on agar.  We never make spore syringes that show bacteria or molds etc in our test results with gentamicin. Although on occasion we do accidentally contaminate a batch during the syringe making process, it’s just part of the business. However that error leads to green mold, trichoderma, not bacteria. We only see this error about twice per year so it's rare we make this mistake. We do use batch #’s on all our our syringe labels. There is 80 spore syringes per batch made. We want you to write down the batch #’s of your spore syringes before you throw them away. If we get enough complaints from customers on one particular batch, that tells us the problem is on our end and not the customers end. In that case we will replace them for free along with some free spores for the troubles. Most of the problems in this hobby come from the substrate itself, not the spore syringes. If molds or bacteria are present in the grains and water from the spore syringe is added, it’s going to accelerate the contamination process. This does not mean the mold or bacteria came from the spore syringe itself. We spend a lot of time testing our spore solution before each small batch of spore syringes is made. It’s a big waste of time and money for us if we send out spore syringes that are contaminated. We throw that solution out and take the loss. We are only making spore syringes from batches that went through a 3 week testing process and did pass on agar with gentamicin. If the mycelium looks healthy and vigorous on our agar, it’s going to do great on properly prepared grain. 

These days more and more people are using agar for strain isolation but most people still want to use spore syringes on agar instead of spore prints. Again I remind you, any spore syringe that might show bacteria on agar will 99% of the time not show bacteria when put directly to grain. 

Our policy when customers claim to have a problem with spore syringes is:

  1. We want to the know the batch # on the spore syringe label. If you don’t have this we will not consider replacing it. 
  2. What kind or color of contamination are you seeing?
  3. Are you using agar or grain? 
  4. Provide pictures of the contamination

We do keep track of any complaints. If no other complaints have come in over the last month then we know it’s not a problem on our end. We will keep your order ID and contact information on file and if several other complaints come in on the same batch # then we will contact you to send out free replacements. The only sure way we know if the problem spore syringe batch is on our end and not yours is when lots of customers mention the same batch # is bad. Thus we require that batch # from you if you want us to consider replacing it for free.

Mushrooms.com and all of our associates through our supply chain has been working with mushrooms for over 2 decades! There is over 100 years of experience if you combine all of our time in this field. This is not some new business or hobby for us and we take a lot of pride in quality and great genetics and clean viable spores and cultures.

I will also address spores that do not germinate. There are several factors that can cause this. Extreme weather in the winter or summer can kill the spores. This is more common in spore syringes than spore prints. In the winter, frozen spore syringes creates ice crystals in the spore solution that usually kills the spores. In the summer, extreme heat for long periods of time can damage or kill the spores. Such as leaving your spores in the mail box for too long in the hot summer sun. Other factors do include bacteria in the substrate that will prevent mycelium from growing. As well too wet or to dry of a substrate can stunt or stop growth. Also not having your temperature correct for the species can cause spores not to germinate. For example cold weather species need much cooler temps then sub tropical species just to germinate. Temperatures can be adjusted after the spores germinate. 

We want you to be successful with your hobby and be blessed with muShrooms. There are so many variations to this hobby that can cause a mushroom project not to work. We have failed grows all the time, like around 5%. Mushroom mycelium contaminates easily indoors, it’s just the nature of domesticating a wild fungi. 

Out in nature mycelium has natural microorganisms protecting and working with the fungi. That symbiotic relationship with nature is lost when the mycelium is grown indoors, thus it has potential to contaminate. We do offer discounted replacements on spore syringes when your project fails so keep that in mind. However we will not replace spore syringes for free unless we are convinced the problem was on our end after many customer complaints of the same batch number. We will also not replace spore syringes just because they showed bacteria on agar or LC solution. When a bad batch of spore syringes is sent out on our end, we usually get 10 to 20 complaints over a 2 to 3 week period. Once number 4 comes in we will consider it an issue on our end send you out a free replacements. If you don’t want to wait, we will replace them for you for $10 each plus shipping. Or option 2, you can make a new order and we will match a free spore syringe with a paid spore syringe. Our policy here is to replace with the same strain you had an issue with.

Another tip about storage of colonizing grain jars. They should not be stored 2 feet from the floor or near air vents. This will greatly reduce the risk of your grain getting contaminated. They should be stored in clean areas away from foot traffic and preferably draft free. Don’t fret if your project fails, set backs in this hobby happen all the time. Blessed are those who persist and have patience with mushrooms :)

Is mushrooms.com secure?

Yes. We have put in extra security features in to Mushrooms.com to ensure your information is encrypted and private.

  • We have installed professional security scripts to prevent hackers from injecting malicious code in to mushrooms.com.
  • Mushrooms.com is NOT on a cheap shared IP hosting plan with other web sites as we have our own server hosted by a highly reviewed and respected company that monitors the servers 24/7 for hackers. We also pay a professional security firm to harden our server and make it more secure and monitor it. Having a web site on cheap shared IP plan is one way hackers inject malicious code at the server level. We learned our lesson the hard way about this once at our previous web site. Never again.
  • We use an SSL encryption for all the data that is sent between our order form, your bank and our gateway service. It's extremely rare you ever hear of SSL's getting hacked. You can always see a web site SSL is working by looking in the URL bar for a pad lock symbol or the URL address. Also the URL will be httpS instead of http. 
  • Our email is run through ProtonMail. This is based in Switzerland and is considered the most secure and private email service available. It's using state of the art end to end encryption for ProtonMail users. You can sign up for a free anonymous account with ProtonMail. Even this service does not have the keys to read our emails and they are transmitted encrypted through our internet provider, like a VPN. If you send us an email from a non ProtonMail account it will be encrypted to us, but our reply to you will not be encrypted on your end unless using a ProtonMail account. Our email also accepts PGP encryption keys. 

We have taken a lot of measures to secure your data and your information, and we are always looking for new innovation in security to add to Mushrooms.com. Also to remember, psilocybe mushroom spores do not contain any illegal drugs and they are legal. Johnny Law is not going to come knocking on your door for ordering spores. In our 21+ years of doing business none of our customers have ever been harassed by the police. That in itself would be illegal.

I can't get past your reCAPTCHA at check out help! 

reCAPTCHA looks for normal human interaction with this web site such as mouse movements, scrolling, reading,  button clicks etc. If you go straight to a check out page or straight to create an account like a bot would, it will probably stop you. Try to scroll a little first first like a human. We have the protection set very low but if you still can't get past it let us know. The owner even got flagged once but he went straight to making a test order instead of scrolling around first. reCAPTCHA is there to protect us and you from malicious interaction with bots trying to steal data.

Can you help me identify a wild mushroom? 

NO. There is no way we could properly ID a mushroom through email. Please check out our book section for some awesome books written by professionals at identifying wild mushrooms. There is also some good forums in the online mushroom community for this. Such as the Shroomery Mushroom Hunting and Identification forum and Mushroom Observer.

Who do I make the money order payable to?

Please leave it blank. It's important you don't write your name on the Pay To line or any scribble or chicken scratch. We can not deposit those and we will have to return it to you. This is why we request it blank so we know it gets filled in correctly. 

Do you accept personal checks? 

NO. We will return it to you because too many customers sent us bad checks in the past. This also goes for bill pay sent through your bank. These are no different then a check and causes us a lot of extra time having to make special trips to the bank to deposit them and then watch to make sure they clear. Please no bill pay checks!

What is the business name on packages you send?

T M T  It says nothing about mushrooms or spores on the outside of your package.

Can I mail in my order and not use your cart system?

Yes but we prefer you do not. Mailing in orders not in our cart system brings on a new set of problems. 

  • We sort of use a live inventory system. 
  • We use coupon codes and specials that change weekly and some of those coupons are for limited supply items. 
  • It’s difficult to read some customers writing then the wrong address might get input. 
  • To many times customers like to make up there own prices or they don’t understand our specials and discounts. 
  • Or they forget to include shipping

It still puzzles us why some customers don’t want to use our nice easy shopping cart? If you really feel the need to bypass our cart system then understand this.

  • If we run out of your first choice before your letter arrives, we will inlclude similiar strains as replacments (It's best to include alternate choices)
  • We will honor the buy x get y free discounts. 

Place all your items in the cart, fill in your information etc, then take a screenshot and print that out and mail it in. 

Thanks for understanding, now please use our cart and make life easy on both of us.  

What is General Delivery?

General delivery is a service the US Post Office offers to people who are in between addresses. Every city has at least one post office who accepts general delivery, usually the main post office. Not all post offices accept gernal delivery, call ahead. Basically a package is sent to that post office address in care of your name. You then show and ID at the post office to pick up your package. Example;

Care of Mark Adams (your name here)

General Delivery (is the street address)

Chandler AZ. 85225

General Delivery is also a great option in the summer if you live in a hot climate as spores can not sustain hot temperatures for long periods of time. It’s best to have them wait in the cool air conditioned post office. This is also a good idea during periods of freezing temperatures during winter. 

To find out which U.S. Post Offices offers General Delivery services use this link and check the General Delivery service option.  

Are mushroom spores and cultures sensitive to high heat or freezing?

YES! We have covered this more extensively in our delivery information FAQ.

Can I call you to place an order OR ask questions? 

Not at this time.  Sorry we are not a phone order company at this time. We can not accept debit cards over the phone. Use the CONTACT US form at the bottom of the web site or if on a mobile phone it's under UTILITY PAGES > CONTACT US.  

Can I mail you a letter to ask questions?

Yes. Even in a digital age people still like to send letters and that is ok. We will write you back and snail mail it. :)

Our address is:


PO BOX 7360

Chandler AZ 85246

How do I screw the needle on to the syringe?

There is a small plastic nipple screwed into the end of the syringe barrel to hold the spore or culture solution in the syringe. Remove that first, then the needle will screw on. We use a high quality BD 10CC syringe, usually filled to 11cc's. BD's can be sterilized and reused again many times over. They come with a 1.5" 16 gauge needle. The needles come factory wrapped and sterile.


YES! We do ship spore prints to select countries. You can find more information about this in our DELIVERY INFORMATION FAQ.

If you did not find the answer to your question in this FAQ there is a lot more questions answered in our DELIVERY INFORMATION FAQ. Please read that before emailing us. Thank You. There is a lot more information regarding shipping in our DELIVERY INFORMATION FAQ

Do you ship Psilocybe Mushroom Spores to California, Georgia or Idaho? 

No, because psilocybe mushroom spores have been banned to import in these 3 states we will not ship there. Our cart will not allow checkout SHIPPING to these 3 states. BILLING addresses to these 3 states is OK.  Gourmet mushroom cultures and spores we can ship to these states and the cart will not block those items.
