Strain Highlight: Psilocybe cubensis 'Golden Mammoth'

The Golden Mammoth strain of Psilocybe cubensis, also referred to as GM, is a remarkable variety known for its rich golden hues, colossal size, and robust psychedelic effects.

History and Origins

The Golden Mammoth strain was developed by a Canadian mycologist known as 'Sporepod' in the late 2000s. The strain was created through meticulous selection and breeding of healthy and vigorous mushroom genetics, ultimately leading to this unique and highly potent variety. Despite being a relatively new strain, Golden Mammoth has quickly made a name for itself in the mycological community.

Physical Characteristics

Golden Mammoth lives up to its name in several ways. The mature mushrooms are typically larger than many other cubensis strains, earning it the 'Mammoth' moniker. The fruiting bodies display broad, often bell-shaped caps that exhibit rich, golden hues that shine under light, and these caps flatten out as the mushrooms mature.

The gills underneath the cap start as a light gray, transitioning to a dark purplish-black as the spores mature. The spore print of the Golden Mammoth is also a dark purple-brown, consistent with most Psilocybe cubensis strains.

The stems of the Golden Mammoth are sturdy and elongated, exhibiting the same golden color as the cap. As with other psilocybin-containing mushrooms, they bruise a blue to bluish-green color when damaged.


Golden Mammoth is a mycologist's dream due to its vigorous mycelial growth, resilience against contaminants, and prolific fruiting. It readily colonizes various substrates, including grain, manure, straw, and coir-based substrates. The strain's mycelium is robust and white, displaying a rhizomorphic growth pattern that indicates a healthy substrate colonization.

Golden Mammoth is particularly well-regarded for its high yield. Under optimal conditions, it can produce an impressive amount of large fruiting bodies, making it an attractive choice for cultivators looking for a high-yielding, potent strain.


Like most Psilocybe cubensis strains, the primary active compounds in the Golden Mammoth are psilocybin and psilocin. Users often report potent and well-rounded psychedelic effects, including intense visual and auditory enhancements, profound introspective thought, and a deep sense of connection to the world around.

The intensity of the effects largely depends on dosage, individual physiology, and environmental factors. However, many users report that the Golden Mammoth provides an experience that leans toward intense visual and sensory enhancement.


The usual dosage for dried Golden Mammoth mushrooms 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 with all psychedelic substances, it's advisable to start with a lower dose and gradually increase in subsequent experiences, adjusting for individual tolerance and comfort level.

Final Thoughts

The Golden Mammoth strain offers an impressive combination of physical beauty, vigorous growth, and potent psychedelic effects. Its remarkable size, golden coloration, and potent experience make it an outstanding selection for cultivators and psychonauts alike.

Always remember to stay aware of your local laws regarding the cultivation and possession of Psilocybe cubensis, including the Golden Mammoth strain. Safety and respect for these powerful substances should always be a priority. Always consider set (mindset) and setting (environment) when planning a psychedelic journey.
