When researching Psilocybe cubensis spores, two legendary strains dominate almost every discussion: Golden Teacher and Penis Envy.
Both belong to the same species, yet they differ in their mushrooms, genetics and spore production, although their spores look alike under the microscope. Because of these differences, researchers and collectors often compare the two when studying cubensis varieties.
In this UK-focused guide, we’ll explain how Golden Teacher and Penis Envy compare: their history, their microscopy characteristics (their spores look alike), and which strain may be more suitable for different types of research.

Golden Teacher vs Penis Envy: Quick Overview
Although both strains belong to Psilocybe cubensis, they display noticeably different characteristics.
| Feature | Golden Teacher | Penis Envy |
| Species | Psilocybe cubensis | Psilocybe cubensis |
| Mushroom spore drop | High | Often lower |
| Microscopy Popularity | Very high | High but more niche |
| Beginner Research | Ideal | Better for advanced study |
| Genetic Stability | Generally stable | Greater mutation variance |
The History of Golden Teacher
Golden Teacher spores are among the most recognised cubensis varieties in the global mycology community.
First widely distributed during the 1980s, this strain became popular because of its:
- Distinct golden-coloured caps
- Tall, elegant stems
- Reliable spore production
Researchers frequently favour Golden Teacher for several reasons.
Genetic Stability
Golden Teacher is one of the most well-documented cubensis strains, and its fully-opening cap releases spores freely, making it a reliable choice for comparative microscopy studies.
Heavy Spore Drop
Golden Teacher mushrooms are often described as heavy spore depositors, leaving a dark purple-brown spore print.
That’s a fact about the mushroom’s natural spore drop. It doesn’t change what’s in a syringe: every Tripping Store syringe has the same concentration, whatever the strain.
Educational Value
Because it is so well documented, Golden Teacher remains one of the most recommended cubensis strains for beginners studying microscopy.
The Unique Genetics of Penis Envy
Among cubensis varieties, Penis Envy is considered one of the most unusual genetic lines.
It originated from a stabilised mutation, resulting in a mushroom with dramatically different physical traits compared to typical cubensis strains.
Instead of the classic cubensis appearance, Penis Envy varieties are known for:
- Thick, dense stems
- Compact structures
- Smaller or partially closed caps
These unusual traits make Penis Envy a fascinating subject for morphological and genetic research.
Why Penis Envy Mushrooms Drop Fewer Spores
Unlike most cubensis strains, Penis Envy mushrooms often have caps that remain partially closed.
Because the gills are less exposed, they tend to release fewer spores.
This is a fact about the mushroom’s natural spore drop only. It doesn’t affect a syringe or a slide: every Tripping Store syringe, Penis Envy included, is prepared using a fixed number of spore prints per batch, giving a consistent double-density suspension, so each strain’s syringe has the same concentration.
Potency Discussions in Research Communities
In cultivation discussions, Penis Envy is often described as producing higher alkaloid concentrations than typical cubensis varieties.
These discussions usually focus on compounds such as:
- Psilocybin
- Psilocin
- Baeocystin
Some laboratory analyses have suggested that certain Penis Envy genetics may contain significantly higher tryptamine concentrations compared with standard cubensis strains.
However, for microscopy research, potency is not the relevant factor. Instead, researchers study:
- Spore morphology
- Genetic consistency
- Structural traits
- Strain comparison
Microscopy: Why the Spores Look Alike
Under the microscope, Psilocybe cubensis spores are smooth, brown to purple-brown and oval, with some looking slightly angular or six-sided face-on. Each has a thick wall and a small pore (germ pore) at one end.
Spores from both strains are about 11.5–17 µm long and 6–11.5 µm wide, the normal Psilocybe cubensis range.
Both strains are Psilocybe cubensis. Strains are cultivated varieties, not separate species, and their spores overlap in size, shape and colour, so you can’t tell Golden Teacher from Penis Envy by its spores. Spores in any sample show a little natural variation in size and outline from spore to spore. That’s normal for the species, not a sign of a particular strain.
If spores look paler or darker than you expect, the cause is usually your setup: how dense the drop is, focus, light brightness, condenser setting, mounting liquid or camera white balance.
The real differences between these two strains are in the mushrooms, covered below.
Which Strain Suits a First Microscopy Study?
For those beginning microscopy research, Golden Teacher is usually the preferred option.
Reasons include:
- Well-documented morphology
- Widely available reference material
Penis Envy may be more suitable for researchers interested in:
- Genetic mutations
- Morphological anomalies
- Advanced cubensis strain comparison
Visual Differences Between the Strains
While spores appear similar under a microscope, the fruiting bodies of these strains show dramatic differences.
Golden Teacher typically displays:
- Tall stems
- Broad caps
- Golden colouring
Penis Envy varieties are recognised by:
- Thick stems
- Dense structures
- Smaller or partially closed caps
These characteristics are what originally led to the strain’s unusual name.
Psilocybe cubensis Spores and UK Law
In the United Kingdom:
- Psilocybin-containing mushrooms are illegal.
- However, spores are commonly sold for microscopy and research purposes only.
Researchers and collectors should always ensure they follow current UK laws and regulations before purchasing any spore samples.
Choosing the Right Strain for Your Research
Selecting between Golden Teacher and Penis Envy depends largely on your research goals.
Golden Teacher May Be Ideal If You Want
