Quick answer: Yes. Illinois lists psilocybin and psilocyn in Schedule I of the Illinois Controlled Substances Act (720 ILCS 570/204), and the words “spore,” “mycelium” and “mushroom” appear nowhere in that Act or in the state’s Drug Paraphernalia Control Act. Mushroom spores are legal to buy, own and ship in Illinois for microscopy, taxonomy and educational use.
What is not legal: germinating them. Illinois defines “manufacture” to include propagation, and an Illinois appellate court held in 1982 that growing psilocybin mushrooms is manufacturing a controlled substance. Possession of the mushrooms themselves is a felony at any weight.

What Illinois law says (and doesn’t say)
The Illinois Controlled Substances Act is 720 ILCS 570. Section 204 is Schedule I, and subsection (d), the hallucinogens, lists “(16) Psilocybin” and “(17) Psilocyn.” The preamble to that list controls “any material, compound, mixture, or preparation which contains any quantity of” those substances.
That is where the mushroom compounds live in Illinois law. Spores are not mentioned anywhere in section 204, in the definitions in section 102, in the possession or manufacturing sections, or in the separate Drug Paraphernalia Control Act (720 ILCS 600). Illinois has never written spores, mycelium or mushrooms into its drug statutes.
The same section shows the difference. When the General Assembly wanted to control a whole organism, it said so: peyote is listed as “all parts of the plant… whether growing or not, the seeds thereof,” and Salvia divinorum gets the same treatment. Psilocybin and psilocyn are listed as chemicals only. They say nothing about seeds or spores.
Why spores are legal when the mushrooms are not
A spore contains no psilocybin and no psilocyn. Schedule I reaches material that “contains any quantity” of a listed substance; a spore contains none, so it is not a Schedule I material. The federal government reached the same conclusion: on January 2, 2024, the DEA’s Drug & Chemical Evaluation Section confirmed in writing that mushroom spores that do not contain psilocybin or psilocin are not controlled, and that the material becomes controlled once it contains psilocybin or psilocin, for example after germination. Our state-by-state guide covers the federal letter in detail.
The line in Illinois is the same as the federal line: the spore is legal; the germinated material is not.
The Illinois case that settled “growing is manufacturing”
Illinois is one of the few states with an appellate decision directly on point. In People v. Dunlap (1982), a Williamson County trial court had ruled that merely cultivating Psilocybe mushrooms was not “manufacturing” a controlled substance. The appellate court reversed. It quoted the statutory definitions, “manufacture” includes “propagation,” and “production” means “planting, cultivating, growing, or harvesting,” and held that growing plant matter containing a controlled substance is prohibited. The court added that “any material which contains any quantity of psilocyn means exactly that.”
The opinion never mentions spores; the defendant was growing mushrooms. But it draws the Illinois line precisely where the DEA draws the federal one. Spores in a syringe are not manufacturing anything. Spores that have been germinated are.
Penalties for the mushrooms themselves
Illinois does not list psilocybin by name in its weight tiers, so mushrooms fall under the general Schedule I provisions, and the weight that counts is the whole “substance containing” the drug, not the psilocybin inside it.
- Possession (720 ILCS 570/402(c)): a Class 4 felony at any weight, one to three years in prison and a fine of up to $25,000. There is no misdemeanor tier for psilocybin in Illinois.
- Manufacture or delivery (720 ILCS 570/401): under 50 grams is a Class 3 felony (two to five years, fine up to $150,000); 50 to under 200 grams is a Class 1 felony (four to fifteen years); 200 grams or more is a Class X felony (six to thirty years, no probation). Because “manufacture” includes propagation, germinating spores is charged here, not as possession.
The Illinois Supreme Court’s 1997 decision in People v. Shapiro shows how the weights work in practice: the defendants were charged with possessing, with intent to deliver, “200 grams or more of a substance containing psilocybin,” the whole-mushroom weight.
The Drug Paraphernalia Control Act
Illinois has a separate paraphernalia statute, 720 ILCS 600, and it is the provision that matters most to a spore buyer because it turns on intended use.
- The definition (section 2) covers equipment “intended to be used unlawfully in planting, propagating, cultivating, growing, harvesting, manufacturing… a controlled substance.” It also reaches “any item whose purpose, as announced or described by the seller, is for use in violation of this Act.” A seller’s own words can make an ordinary object paraphernalia.
- Possession (section 3.5) is a Class A misdemeanor with a $750 minimum fine, but the possession offense is written around items for ingesting a controlled substance or preparing it for use. It does not list cultivation.
- Sale (section 3) is a Class 4 felony with a $1,000 minimum fine per item; sale to a minor is a Class 3 felony.
- Two provisions cut the other way. Section 4 exempts items used “as an incident to lawful research, teaching, or chemical analysis and not for sale,” and items “historically and customarily used” with any lawful substance. Section 6 instructs that “all reasonable and common-sense inferences shall be drawn in favor of the legitimacy of any transaction or item.”
A syringe of spores sold for microscopy, with no cultivation instructions and no cultivation supplies, is not paraphernalia under this Act; a spore syringe sold with a grow kit and a description of how to use it would be. This is why we sell spores for microscopy only, do not provide cultivation instructions, and cancel orders from customers who tell us they intend to cultivate.
Chicago, Evanston, Lake County: any local decriminalization?
No. No Illinois city or county has adopted a psilocybin decriminalization or deprioritization measure.
- Chicago. Alderman Brian Hopkins introduced a non-binding resolution (R2019-735) in October 2019 asking the state to reduce penalties. A council committee heard it in January 2020 and it was never adopted.
- Evanston. A 2022 proposal to make entheogen offenses the city’s lowest enforcement priority was voted down in committee in 2023, with the city’s attorney noting that a city “cannot change what the state has deemed a felony.”
Note that the Paraphernalia Control Act expressly allows municipalities to adopt equal or stricter paraphernalia ordinances (section 7), so local rules can be tighter than state law, never looser. None of the ones we checked mention spores.
The CURE Act and the 2026 Psilocybin Advisory Board bill
Illinois has not passed any psilocybin reform.
- The CURE Act (Compassionate Use and Research of Entheogens Act) would create a regulated psilocybin-services program and remove psilocybin and psilocyn from Schedule I. Illinois lawmakers have introduced the CURE Act in two General Assemblies. In 2023–24, HB 1 and SB 3695 never got a floor vote and died when the session ended. In 2025–26, HB 1143 and SB 2184 have stalled in committee; both were re-referred to committee on March 27, 2026, and a separate pilot-program bill, HB 2992, stalled the same day.
- SB 2772, a narrower bill that would only create an Illinois Psilocybin Advisory Board to study the question and report within 18 months, passed the Senate 41–13 on May 7, 2026, then was sent to the House Rules Committee on May 15, 2026, where it has sat since. The fall veto session (November 17–19 and December 1–3, 2026) is its only remaining chance this year.
None of these bills mentions spores, and none would change the status of spores, which are already legal. Illinois has no citizen-initiative route for a drug law; the constitution limits statewide initiatives to changes in the structure of the legislature.
Buying spores in Illinois
- It is legal to buy and own Psilocybe cubensis spores in Illinois for microscopy, taxonomy and educational use.
- Ordering online is legal. Federal mail rules bar controlled substances and paraphernalia; spores are neither. Illinois orders ship the same business day.
- Use spores for study only. Illinois’s paraphernalia statute turns on intended use, and its manufacturing statute turns on germination. Spores for microscopy are a legal hobby; anything that points toward cultivation is where the law starts.
