Strain Highlight: Psilocybe cubensis 'Koh Samui Super Strain'

The Psilocybe cubensis 'Koh Samui Super Strain', often referred to as KSSS, is an exciting variant of the psilocybin-containing fungi, known for its unique origins, robust growth characteristics, and profound psychedelic effects.

History and Origins

The Koh Samui Super Strain was first discovered on the island of Koh Samui in Thailand. This strain is an isolation from the original Koh Samui strain, obtained from buffalo dung samples collected by mycologist John Allen. The 'Super Strain' designation indicates its notable vigor and larger size compared to the original Koh Samui strain.

Physical Characteristics

The KSSS typically produces medium to large fruiting bodies with a distinctive appearance. The caps are often bell-shaped in younger mushrooms, flattening out and occasionally showing an uplifted rim in maturity. These caps exhibit a caramel or light golden-brown color, sometimes with a slightly darker umbo.

Underneath the cap, the gills transition from a light grey in young specimens to a dark purplish-black in mature mushrooms as the spores develop. The spore print of the KSSS is also a dark purple-brown, in line with most Psilocybe cubensis strains.

The stems of KSSS are usually elongated and robust, displaying a creamy white to light yellow color. As with other psilocybin mushrooms, they exhibit a bluing reaction when bruised or damaged, indicating the presence of psilocybin.


KSSS is widely recognized for its robust mycelial growth and consistent fruiting. The mycelium readily colonizes a variety of substrates, including grain, manure, straw, and coir-based mixtures, often displaying a dense, white, and rhizomorphic growth pattern.

The Koh Samui Super Strain is particularly praised for its resistance to varying environmental conditions. Its origin in the humid, tropical climate of Thailand means it tends to perform well in warmer temperatures and higher humidity, making it a popular choice for cultivators in similar climates.


As a variant of Psilocybe cubensis, the primary active compounds in KSSS are psilocybin and psilocin. These compounds can elicit a wide range of effects, including visual and auditory enhancements, shifts in perception, and deep emotional introspection.

Users often report that the KSSS strain provides a balanced, well-rounded psychedelic experience, characterized by a heightened sense of creativity, a feeling of connection to the world, and introspective insights. As with all psychedelics, the intensity of the effects can vary greatly depending on dosage, individual sensitivity, and the environment.


The recommended dosage for dried KSSS mushrooms typically ranges from 1-2.5 grams for beginners, 2.5-5 grams for intermediate users, and 5 grams or more for those with extensive experience. As the potency can vary among individual mushrooms and different growing conditions, it's always advisable to start with a lower dose and increase gradually in subsequent experiences.

Final Thoughts

The Psilocybe cubensis 'Koh Samui Super Strain' is a unique variant within the Psilocybe family, with its tropical origins, robust growth characteristics, and powerful psychedelic effects. This strain's adaptability and resilience make it an appealing choice for cultivators, while its profound effects are highly valued by psychonauts.

It's important to note that cultivation and possession of Psilocybe cubensis, including the KSSS strain, may be illegal in some regions. Always familiarize yourself with local laws before cultivating or consuming these mushrooms. When planning a

psychedelic journey, consider set (mindset) and setting (environment) and approach with respect and safety as the top priorities.
