By using themushieunderground.net or buying from us, you agree to these Terms of Service. If you don’t agree, please don’t use the site or place an order.
1. Agreement, Eligibility, and Changes
Who we are. The Mushie Underground (“TMU,” “we,” “us”) operates themushieunderground.net (the “Site”) and sells mycology supplies, including liquid cultures, syringes, and related growing materials (the “Products”).
Eligibility. You must be at least 18 years old, or the age of majority where you live, to place an order. By ordering, you confirm that you can form a binding contract and that you are not barred from buying our Products under the laws of your location.
Changes. We may update these Terms at any time. The updated version takes effect when we post it on the Site, and the date at the top shows when it was last revised. Continued use of the Site after a change means you accept it. Orders are governed by the Terms in effect when you place them.
2. Products, Intended Use, and Legal Compliance
What we sell. Our Products are mycology supplies for lawful hobby, culinary, educational, and research cultivation. Examples include culture syringes (such as our 10 mL Blue Oyster liquid culture syringe kit), needles, swabs, and related accessories. Syringe kits ship with a separate needle and alcohol swab, and are not sterile once you open and use them.
Product information. Descriptions, images, and growing guidance on the Site are general information only. Colors, packaging, and labeling may vary slightly from what is shown, and living cultures vary naturally between batches.
Species we sell. We sell only non-controlled mushroom species. We do not sell psilocybin-containing species, and nothing on the Site is an offer to supply any controlled substance.
Your legal responsibility. You are responsible for knowing and following the laws that apply where you live, including rules on possessing, cultivating, or shipping fungal cultures and on needles and syringes. We may decline or cancel any order that we believe would break the law, and we may ask for additional information before we ship.
Needles and syringes. Needles included with our Products are for inoculating cultures only. You agree to use and dispose of them safely and in line with local rules, and never to use them on people or animals.
3. Orders, Pricing, Payment, and Shipping
Orders. Placing an order is an offer to buy. We accept it when we send a shipping confirmation, and we may refuse or cancel any order, for example because of stock limits, pricing errors, suspected fraud, or legal concerns. If we cancel a paid order, we refund you in full.
Pricing. Prices are in U.S. dollars and may change without notice. Prices do not include shipping or applicable taxes unless stated. We do our best to list prices correctly, but if we find an error we may correct it or cancel the order.
Payment. You agree to give accurate, current payment details and confirm that you are authorized to use the payment method. Payments are handled by third-party processors, and we do not store your full card number.
Shipping. We ship within the United States unless the Site says otherwise. Delivery dates are estimates, not guarantees. Orders typically ship within 3-5 business days. Living cultures are sensitive to heat and cold, so we may delay shipping in extreme weather to protect them.
Risk of loss. Risk passes to you when the carrier delivers the package to the address you gave. Please check your shipping address carefully. We are not responsible for packages lost because of an incorrect or incomplete address. If a package is lost or damaged in transit, contact us within 7 days of the expected delivery date and we will work with you and the carrier on a resolution.
4. Returns, Refunds, and Contamination Claims
Living products. Because cultures are living, perishable, and easily contaminated once opened, we cannot accept returns of opened, used, or improperly stored Products. We do not accept returns of needles, swabs, or other items that touch a culture.
Damaged, wrong, or dead-on-arrival orders. If your order arrives damaged, is not what you ordered, or shows clear signs of contamination or failure on arrival, contact us at tmumushieunderground@gmail.com within 7 days of delivery. Include your order number and clear photos. If we confirm the problem, we will replace the Product or refund you, at our choice.
Contamination after use. Contamination after you open or inoculate a culture is usually caused by technique, environment, or substrate, and is outside our control. It is not grounds for a refund. We are happy to help you troubleshoot.
No yield guarantee. Growth speed, yield, and fruiting depend on your equipment, substrate, temperature, humidity, and skill. We do not guarantee any particular result.
Refunds. Approved refunds go back to your original payment method, usually within 5–10 business days. Shipping fees are refunded only when the error was ours.
Chargebacks. Please contact us before filing a chargeback. We will do our best to resolve the issue quickly, and we may dispute chargebacks that conflict with these Terms.
5. Cultivation Risks, Safety, and Prohibited Uses
Assumption of risk. Growing mushrooms involves real risks, including contamination, mold, allergic reactions, respiratory irritation from spores, and cuts or needle-stick injuries. You use our Products at your own risk and are responsible for good hygiene, safe handling, and proper disposal.
Edible mushrooms. Never eat any mushroom unless you have positively identified it and know that it is safe for you. Some people are allergic to or sensitive to mushrooms, even common culinary species. Before eating anything you grow, make sure it is the species you expect and free of mold or contamination. We are not responsible for illness caused by eating mushrooms you grew, foraged, or misidentified. If you have health concerns, talk to a qualified professional.
Not medical advice. Nothing on the Site is medical, nutritional, or legal advice. Our Products are not intended to diagnose, treat, cure, or prevent any disease.
Prohibited uses. You agree not to:
- use our Products to cultivate or produce any controlled or illegal substance
- resell our Products in violation of law, or misrepresent them as your own
- use needles or syringes on people or animals, or in any unsafe way
- scrape, probe, or attack the Site, or try to bypass its security
- place orders with false information or stolen payment details
- use the Site in any way that breaks the law or infringes anyone’s rights
We may suspend or ban anyone who breaks these rules and may report unlawful activity to the authorities.

You give us a non-exclusive, royalty-free, worldwide license to display, reproduce, and use it in connection with the Site and our marketing.

Privacy. Our Privacy Policy explains how we collect and use personal information, and it forms part of these Terms.
Third-party links. The Site may link to outside websites or services, such as payment processors and shipping carriers. We do not control them and are not responsible for their content, policies, or practices.
7. Disclaimers, Limitation of Liability, and Indemnification
Disclaimer. THE SITE AND PRODUCTS ARE PROVIDED “AS IS” AND “AS AVAILABLE.” TO THE FULLEST EXTENT THE LAW ALLOWS, TMU DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT ANY CULTURE WILL GROW, FRUIT, OR REMAIN FREE OF CONTAMINATION, OR THAT THE SITE WILL BE UNINTERRUPTED OR ERROR-FREE.
Limitation of liability. TO THE FULLEST EXTENT THE LAW ALLOWS, TMU AND ITS OWNERS, EMPLOYEES, AND AGENTS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS OR LOST DATA, ARISING FROM YOUR USE OF THE SITE OR PRODUCTS. OUR TOTAL LIABILITY FOR ANY CLAIM IS LIMITED TO THE AMOUNT YOU PAID FOR THE PRODUCT THAT GAVE RISE TO THE CLAIM.
Your legal rights. Some places do not allow certain limits on warranties or liability, so parts of this section may not apply to you. Nothing in these Terms limits rights that cannot be waived under your local law.
Indemnification. You agree to defend and hold harmless TMU and its owners, employees, and agents from any claim, loss, or expense (including reasonable legal fees) arising from your breach of these Terms, your misuse of the Products, or your violation of any law or third party’s rights.
8. Governing Law, Disputes, and Contact
Governing law. These Terms are governed by the laws of the State of California, without regard to conflict-of-law rules.
Resolving disputes. Please contact us first at tmumushieunderground@gmail.com and give us 30 days to try to resolve the issue informally. If we can’t, any dispute will be brought in the state or federal courts located in Los Angeles, CA, and you and TMU consent to that court’s jurisdiction.
