The short answer

Two things are true at the same time, and most confusion about spore law comes from mixing them up.

1. Psilocybin and psilocin — the compounds found in mature mushrooms — are Schedule I controlled substances under federal law and in every state.
2. A spore is not a mushroom. It contains neither compound. So under federal law, and under the law of 46 states, a spore is just a spore.

That is why spores can be sold openly for microscopy while the mushrooms cannot. It is also why the legal line is drawn at germination: once a spore germinates and starts producing mycelium, the material contains the controlled compounds and the law treats it like the mushroom.

Four states decided not to rely on that distinction and wrote spores (and, in three of them, mycelium) directly into their statutes. Those four are the exceptions, and they are covered in detail below. We do not ship Psilocybe spores to any of them.

Why spores are legal when mushrooms are not (federal law)

The Controlled Substances Act lists psilocybin and psilocin in Schedule I (21 U.S.C. § 812; 21 C.F.R. § 1308.11). It does not list spores, and it never has.

On January 2, 2024, the DEA’s Drug & Chemical Evaluation Section put the agency’s position in writing in a letter to attorney Michael McGuire. The letter says that if mushroom spores (or any other material) do not contain psilocybin or psilocin, the material is not controlled under the CSA. It adds one warning, and that warning is the key point: “if at any time the material contains a controlled substance such as psilocybin or psilocin (for example, upon germination), the material would be considered a controlled substance under the CSA.”

In plain English: the spores are legal; the germinated material is not.

Two other federal rules matter to buyers:

• The drug-paraphernalia statute (21 U.S.C. § 863) makes it a crime to sell, or send through the mail, items “primarily intended or designed for use” in producing a controlled substance. Whether an item counts as paraphernalia depends on how it is marketed: the statute tells courts to look at instructions that come with it, advertising, and how it is displayed for sale. This is why legitimate spore vendors sell for microscopy only, do not provide cultivation instructions, and do not bundle spores with cultivation supplies. It is also why “for microscopy use only” appears on everything we sell. It describes the product’s lawful use.
• Mail. USPS Publication 52 bars controlled substances and drug paraphernalia from the mail. Spores are neither, so they ship legally through USPS and private carriers to the 46 states.

Nothing in federal law sets a purchase age for spores. Age limits (18+ or 21+) are vendor policy. We require customers to be adults.

The four states with spore laws

California — restricted (an intent-based law)

Statutes: California Health & Safety Code §§ 11390, 11391 and 11392.

Section 11390 makes it a crime to cultivate “any spores or mycelium capable of producing mushrooms” with intent to produce psilocybin or psilocin. Section 11391 makes it a crime to transport, import into the state, sell, furnish or give away such spores or mycelium “for the purpose of facilitating” that cultivation. Either offense carries up to one year in county jail, or a state-prison term. Section 11392 allows spores to be obtained for bona fide research, instruction or analysis, but only with approval from the state’s Research Advisory Panel.

What it means: California’s law is written around intent. The statute does not say “possessing spores is illegal,” and a microscopist with a slide is not what it describes. But the “imports into this state… sells, furnishes” language is aimed squarely at out-of-state vendors, and no vendor can prove a buyer’s intent. That is why reputable vendors, including us, do not ship Psilocybe spores to California.

Oakland, Santa Cruz, San Francisco, Berkeley, Arcata and Eureka have all told their police to deprioritize psilocybin enforcement. None of those measures amend § 11391 or protect a seller. (Full detail: Are mushroom spores legal in California?)

Florida — restricted since July 1, 2025 (the newest law)

Statute: Florida Statutes § 500.75, created by Senate Bill 700 (Chapter 2025-22), signed May 15, 2025, effective July 1, 2025.

The section makes it unlawful “to transport or offer to transport, import into this state, sell or offer for sale, furnish, or give away spores or mycelium capable of producing mushrooms or other material which will contain a controlled substance, including psilocybin or psilocyn, during its life cycle.” A violation is a first-degree misdemeanor: up to one year in jail and a $1,000 fine.

Two things worth knowing. First, the statute is written against the seller, shipper and importer; it does not name possession. Second, it sits in Chapter 500 of the Florida Statutes (food products), not in Chapter 893 (drug abuse prevention and control). Anyone who searches only the drug chapter for the word “spores” finds nothing, which is why several older guides still list Florida as a legal state. It is not. Vendors stopped shipping spores to Florida in July 2025, and so did we. (Full detail: Are mushroom spores legal in Florida?)

Georgia — banned

Statutes: O.C.G.A. § 16-13-71(b), § 16-13-72 and § 16-13-79.

Georgia’s “dangerous drug” list includes “Mushroom spores which, when mature, contain either psilocybin or psilocin.” Section 16-13-72 makes it unlawful to sell, give away, distribute or possess any dangerous drug except through licensed channels (manufacturers, pharmacists, physicians and so on), and § 16-13-79 makes a violation a misdemeanor. Some websites describe Georgia’s spore offense as a felony; the statute says misdemeanor. (Psilocybin itself is a Schedule I felony in Georgia.) Georgia’s law reaches possession, not just sale. (Full detail: Are mushroom spores legal in Georgia?)

Idaho — banned (the strictest of the four)

Statutes: Idaho Code § 37-2705(d)(34) and § 37-2732.

Idaho lists “Spores or mycelium capable of producing mushrooms that contain psilocybin or psilocin” in Schedule I, right alongside psilocybin and psilocin. Under § 37-2732, possessing a Schedule I non-narcotic is a misdemeanor (up to one year and $1,000), and manufacturing, delivering or possessing with intent to deliver one is a felony (up to five years and $15,000). In Idaho the spores themselves are a controlled substance, so the microscopy distinction does not help. (Full detail: Are mushroom spores legal in Idaho?)

Every state at a glance

Where the “The law” column says No spore statute, the state’s controlled-substance schedule lists psilocybin and psilocin but says nothing about spores or mycelium, so the federal reasoning applies: spores are not controlled. Notes are current as of September 25, 2026.

Count: 46 states legal; 2 restricted (California, Florida); 2 banned (Georgia, Idaho).

A closer look at Illinois and Michigan

Illinois lists psilocybin and psilocin in Schedule I of the Illinois Controlled Substances Act (720 ILCS 570/204) and says nothing about spores or mycelium. Spores are legal to buy and own in Illinois, and in Michigan too (see our Michigan guide).

The mushrooms are another matter: possessing any amount of a psilocybin-containing substance is a Class 4 felony in Illinois, and growing, delivering or selling it is a Class 3 felony or higher depending on weight. An Illinois appellate court held in 1982 (People v. Dunlap) that growing psilocybin mushrooms is manufacturing a controlled substance. Our Illinois guide has the statutes and the case.

Reform has been discussed for years but has not passed. The CURE Act, a regulated psilocybin-services bill (SB 2184), has stalled in committee. A narrower bill, SB 2772, which would create a Psilocybin Advisory Board to study the question, passed the Senate on May 7, 2026 and was sent to the House Rules Committee on May 15, 2026, where it sat when the spring session ended. No Illinois city, including Chicago, has passed a decriminalization or deprioritization ordinance. Nothing in any of these bills would change the status of spores.

Decriminalized cities and states: does that change anything?

Not for spores. Spores were already legal in every one of these places, so a city measure has nothing to add. What the measures change is what happens after germination, and even then only as a matter of local police priority.

• Cities and counties that have deprioritized enforcement include Denver; six California cities (see the list above); Ann Arbor, Detroit, Ferndale, Hazel Park, Ypsilanti and Washtenaw County (Michigan); Washington, D.C.; Seattle, Tacoma, Olympia, Port Townsend, Jefferson County and King County (Washington); seven Massachusetts cities and towns (see the list above); Minneapolis; and Portland, Maine. These are policing-priority statements. None legalizes anything, none binds state or federal officers, and none protects a seller.
• Colorado (Proposition 122, C.R.S. § 18-18-434) gives adults 21+ a limited personal-use allowance under state law and licenses “healing centers.” Any sale remains illegal — the state has sent cease-and-desist letters to businesses selling mushrooms — and the statute never mentions spores.
• Oregon (Measure 109) allows psilocybin only inside licensed service centers, produced by licensed manufacturers. The separate Measure 110 decriminalization was repealed by the legislature effective September 1, 2024, so possession outside the program is a misdemeanor again.
• New Mexico passed the Medical Psilocybin Act in April 2025. It is medical-only, run by the Department of Health, with no personal-use pathway.
• Massachusetts voters rejected Question 4, a legalization measure, in November 2024.

The rule of thumb: state and city reform changes the law around the mushroom, not around the spore. If you are in one of the 46 legal states, spores were legal before the reform and are legal after it. If you are in California, Florida, Georgia or Idaho, no city ordinance overrides the state statute.

What is illegal almost everywhere

These activities are illegal in almost every state.

• Germinating the spores. Mycelium of a psilocybin-producing species contains the controlled compounds. Producing it is manufacturing a Schedule I substance under federal law. Growing psilocybin mushrooms is illegal in almost every state. The narrow exceptions are Colorado’s limited personal cultivation, Oregon’s state-licensed manufacturers, and New Mexico’s future state-permitted medical producers.
• Liquid culture, “isolates” and any live mycelium of a Psilocybe species. These are not spores; they are the controlled substance itself, and California, Idaho and Florida name “mycelium” in their statutes for exactly that reason.
• Kits and supplies marketed for cultivation. Under the federal paraphernalia statute, equipment becomes illegal to sell or mail when it is marketed or “primarily intended” for producing a controlled substance. We do not sell substrate, grain or cultivation kits; our only bundle is spore syringes packed with basic lab-hygiene supplies (gloves, mask, alcohol pads).
• Shipping Psilocybe spores into California, Florida, Georgia or Idaho. Florida and California statutes both use the words “import into this state,” which is aimed at the shipper as much as the buyer.

Frequently asked questions

Can I legally buy mushroom spores?

Yes, in 46 states, for microscopy, taxonomy or educational use. Not in California, Florida, Georgia or Idaho, and reputable vendors will not ship there. Buying is legal because the spores contain no controlled substance; what happens to them afterward is what the law regulates.

Is it illegal to order mushroom spores online?

No, not in the 46 legal states. Federal mail rules bar controlled substances and drug paraphernalia, and spores are neither. Ordering into California, Florida, Georgia or Idaho is where state law applies; two of those statutes specifically cover importing spores into the state.

Do you need a license to sell mushroom spores?

There is no federal license for spores because they are not a controlled substance; a spore vendor needs the same business registrations as any other online retailer. What a vendor must not do is market spores for cultivation or sell them with instructions or cultivation supplies, because that is what turns a legal product into “drug paraphernalia” under 21 U.S.C. § 863. California requires Research Advisory Panel approval for research use, and Georgia and Idaho prohibit sale outright.

Are mushroom grow kits legal?

It depends entirely on what the kit is for. A kit for oyster or lion’s mane mushrooms is legal everywhere. Equipment marketed for cultivating a psilocybin-producing species is drug paraphernalia under federal law, and selling or mailing it is a crime, no matter what is or isn’t in the box. This is why we sell spore syringes for microscopy and nothing for cultivation.

Are Psilocybe cubensis spores legal?

The species does not change the analysis. The four laws are written around what the spores can produce. They cover every Psilocybe species, and every other state’s silence covers every species too. Psilocybe cubensis spores are legal in 46 states and restricted or banned in California, Florida, Georgia and Idaho.

Which states are mushroom spores illegal in?

Georgia and Idaho ban them outright, including possession. California and Florida restrict them: California criminalizes cultivation with intent and selling or importing spores to facilitate it; Florida (since July 1, 2025) criminalizes selling, transporting, importing, furnishing or giving them away.

Are mushroom spores legal in Texas?

Yes. Texas lists psilocybin and psilocin in Penalty Group 2 (Health & Safety Code § 481.103), and the word “spore” does not appear anywhere in Chapter 481. Texas does have a paraphernalia statute (§ 481.125), so the same “microscopy only, no cultivation supplies” rule applies. Our Texas guide has the details.

Are spores legal in Canada, the U.K. or Australia?

This guide covers the United States. In brief: Canada controls psilocybin and psilocin but spores are sold openly; the U.K.’s Class A wording covers fungus that contains psilocin, which does not reach spores; Australia’s treatment of spores is disputed and varies by state. If you are outside the U.S., check your own country’s law before ordering anything.

Why does every vendor say “for microscopy use only”?

Because the federal paraphernalia statute turns on marketing and intended use. Microscopy, taxonomy and education are the lawful uses of spores, so that is what honest vendors sell them for, and it is why we will not answer cultivation questions or ship to customers who ask them.

I live in Denver, Oakland or Ann Arbor. Does decriminalization change anything for me?

Not for spores, which were already legal in your state. The city measures only change local police priorities around the mushrooms themselves. In California, the state spore statute still applies in Oakland, Santa Cruz and every other city.

Did the 2026 federal executive order on psychedelics change spore law?

No. The April 2026 order directs the DEA and HHS to build a right-to-try pathway and to review certain Schedule I substances that have completed Phase 3 trials. It does not legalize or reschedule psilocybin, and it says nothing about spores or cultivation.

Will you tell me if the law in my state changes?

We re-check every statute on this page at least quarterly and note the date at the top. If you know of a bill or a new law we have missed, contact us and we will verify it and update the table.

How we checked, and sources

We read the statutes rather than other websites. For the four restricting states we quote the statute text and link to the legislature’s site or a mirror of the current code. For Texas and Louisiana, the two states most often listed as “unclear” elsewhere, we searched the full text of the controlled-substance chapter for the word “spore.” For every other state we relied on the state schedule’s silence on spores, cross-checked against the Reason Foundation’s 2025–2026 state policy roundups, which track every psychedelic bill filed. Last checked September 25, 2026.
