Quick answer: The quickest way to settle Golden Teacher vs Penis Envy is to look at the shape of the mushroom. Both are strains of the same species, Psilocybe cubensis. Golden Teacher looks like a wild cubensis, with a golden cap that opens fully and drops a dark spore print. Penis Envy has a thick stem and a small cap that stays partly closed, so it releases very few spores. Under a light microscope, the spores of the two strains look the same.
Spores of both strains are legal to buy for microscopy in 46 states. Germinating them is not, which is why this page covers history and identification only.

Two strains of one species
Golden Teacher and Penis Envy are not separate species. Both are Psilocybe cubensis, a dung-loving mushroom that the American mycologist Franklin Sumner Earle first described from Cuba in 1906 under the name Stropharia cubensis. Rolf Singer moved it into the genus Psilocybe in 1949. “Golden Teacher” and “Penis Envy” are strain names, which are informal labels for lines that hobbyists have kept going for decades. No registry certifies either one, and a 2025 review in the Journal of Fungi noted that what is known about named cubensis strains comes mostly from “non-academic, community-based reports.”
The two strains are also closer genetically than their shapes suggest. A 2023 genome study in Current Biology, which compared cultivated and wild magic mushrooms, found that cultivated cubensis strains carry very little genetic diversity. The differences described below are real and easy to see, but they are differences between closely related lines of one species.
Where each strain came from
Golden Teacher. Nobody recorded where Golden Teacher came from. The most repeated account, found in community wikis and strain guides, says it was found in Florida in the 1980s. No collector’s name, date or specimen has ever been produced, so the Florida story is tradition rather than record. A 2021 DoubleBlind history makes the same point from another angle: Golden Teacher and B+ have a “long and mostly forgotten history” that probably predates the online growing forums of the late 1990s. What is not in doubt is its standing today. It is the best-known cubensis strain, and our Golden Teacher guide covers its history in more detail.
Penis Envy. Penis Envy has a better-documented history, although it still rests on memory. The spores behind it trace back to wild cubensis that Terence McKenna collected in the Amazon in the early 1970s. An older story, still repeated on many websites, credits Steven Pollock with isolating the strain. The account now most cited comes from Rich Gee (Richard Gutierrez), a cultivator who says he received the Amazonian spores in the 1970s through his friend Jules Stevens, who got them from someone with direct access to McKenna’s collection. In Gee’s telling, Pollock was not the source. Gee says one line in the culture carried a mutation that kept the cap from opening properly, and that he stabilized that form by cloning it. His version is first-hand, but no dated record backs it up. Our Penis Envy guide covers both versions of the story.
How the names came about
The “Golden” in Golden Teacher describes the cap, which is golden to amber-yellow on a mature mushroom. The “Teacher” part has no documented origin. Nobody has tied it to a person, a date or an event, so it is best treated as folklore. The name is often shortened to GT.
Penis Envy is named for its shape, and here the story is specific. According to Gee, the mushrooms were still called “Amazons” in 1977 when he showed them to a group of strippers, who said they looked like “donkey dongs.” The phrase “penis envy” came up in that exchange, and the name stuck. The same naming habit carried into later lines, the best known being Albino Penis Envy.
Golden Teacher vs Penis Envy: what the mushrooms look like
For identification, Golden Teacher vs Penis Envy is one of the easier comparisons in the hobby, because the two strains separate by shape, even in photographs.
- Golden Teacher has the classic cubensis form. The cap is golden to amber-yellow, usually darker at the center, and it starts as a rounded dome and broadens to a flat top as the mushroom matures. The stem is white to pale yellow and of ordinary proportions, with a white ring that darkens as spores fall on it. DoubleBlind describes Golden Teacher as looking much more like wild cubensis than Penis Envy does.
- Penis Envy has a thick, dense stem and a small, rounded cap that often stays partly closed at maturity, so the edge of the cap sits close to the stem. Because the cap does not open fully, much of the gill surface stays covered. The overall look is short and heavy, and it does not resemble a typical wild cubensis.
If a photo shows a mushroom with an open, flat, golden cap on an ordinary stem, it is not Penis Envy. If it shows a thick stem with a small cap still wrapped around the top, it is not a typical Golden Teacher.
Spore prints and spores
This is where the practical difference for a microscopist shows up. A Golden Teacher cap opens fully and drops a dense, dark print. DoubleBlind describes the strain as dumping “a thick carpet of purple-black spores.” That matches the species as a whole, whose gills darken to purplish-black as the spores mature and whose ring usually takes on the same color from falling spores.
Penis Envy produces very few spores. Its cap stays partly closed and its gills are small, so prints are faint or hard to collect at all. That is why the strain has been kept going by cloning rather than by spores, and why a Penis Envy spore syringe normally holds fewer spores than a Golden Teacher spore syringe. A lighter-looking Penis Envy syringe is a trait of the strain, not a sign of a bad fill. Our guide to what a spore syringe is explains why the look of the liquid varies from strain to strain.
Under a light microscope, the spores themselves look alike. Published descriptions of P. cubensis give spores roughly 11 to 17 micrometers long, smooth, sub-ellipsoid (an oval flattened on one side) and with a germ pore at one end. The traits that set Penis Envy apart are in the fruit body, and no published description separates Golden Teacher and Penis Envy spores by size or shape. If you had two unlabeled slides, you could not tell the strains apart from the spores alone. The difference you would notice is how many spores you find in a drop.
Side-by-side comparison
The table lines up the two strains on the points that matter for identification.

| Origin | Said to come from Florida in the 1980s; undocumented | Amazonian spores from the early 1970s, stabilized by Rich Gee (his account) |
| Name | “Golden” for the cap; “Teacher” is folklore | Named for its shape in 1977, by Gee’s account |
| Cap | Golden to amber-yellow, opens flat | Small and rounded, often stays partly closed |
| Stem | White to pale yellow, ordinary proportions | Thick and dense |
| Spore print | Heavy, dark purple-brown | Faint or hard to collect |
| Spores under a microscope | Typical cubensis, plentiful | Typical cubensis, sparse |

Legal status of both strains
Golden Teacher and Penis Envy spores contain no psilocybin or psilocin, so under federal law and the law of 46 states they are not a controlled substance; the DEA confirmed the federal position in writing in January 2024. California and Florida restrict spores, Georgia and Idaho ban them, and we do not ship Psilocybe spores to those four states. Germinating spores is illegal under federal law everywhere. Laws change, so check the current law where you live. Our state-by-state legal guide has every statute.
Frequently asked questions
Are Golden Teacher and Penis Envy the same species?
Yes. Both are Psilocybe cubensis. Golden Teacher and Penis Envy are informal strain names for two lines of that one species.
How can you tell Golden Teacher and Penis Envy apart?
Look at the shape. Golden Teacher has a golden cap that opens flat on an ordinary stem. Penis Envy has a thick, dense stem and a small cap that often stays partly closed.
Can you tell Golden Teacher and Penis Envy spores apart under a microscope?
No. Both produce ordinary cubensis spores, roughly 11 to 17 micrometers long and sub-ellipsoid with a germ pore. The practical difference is that Penis Envy spores are much harder to find because the strain makes so few of them.
Why does a Penis Envy spore syringe look lighter than a Golden Teacher syringe?
Penis Envy releases very few spores because its cap does not open fully, so its syringes hold fewer spores. That is a trait of the strain, not a fault in the syringe.
Who created Penis Envy?
By his own account, Rich Gee (Richard Gutierrez) stabilized the strain in the 1970s from Amazonian spores that traced back to Terence McKenna. An older story credits Steven Pollock, but Gee says Pollock was not the source.
Where did Golden Teacher come from?
It is usually said to have been found in Florida in the 1980s, but no collector, date or specimen has ever been documented. Treat the origin story as tradition.
Are Golden Teacher and Penis Envy spores legal?
Yes, for microscopy, in 46 states. California, Florida, Georgia and Idaho have their own spore laws, and we do not ship to those four states.
