For nearly a century, scientists have been aware that certain morning glory plants contain powerful psychoactive compounds closely related to LSD. These plants have been used ceremonially for generations and studied scientifically since the early twentieth century, yet a fundamental mystery remained unresolved. Plants do not produce ergot alkaloids on their own, and these chemicals are known to originate exclusively from fungi. This contradiction led researchers to suspect that a hidden fungal partner was responsible, one that lived in intimate association with the plant and quietly produced the compounds that fascinated chemists, botanists, and psychonauts alike.

That mystery has finally been solved. In June 2025, scientists confirmed the discovery and full genome sequencing of a previously unknown fungal species living inside morning glory plants. The fungus produces ergot alkaloids that closely resemble the chemical backbone of LSD, confirming a hypothesis that dates back to the work of Swiss chemist Albert Hofmann. Beyond its historical significance, this discovery opens the door to new pharmaceutical research, deeper insight into plant–fungus symbiosis, and a renewed appreciation for how biological intelligence often hides in places we overlook.
The Discovery Hidden in Plain Sight
The discovery took place at West Virginia University, where environmental microbiology student Corinne Hazel was studying how morning glory plants distribute defensive chemicals through their roots. While examining seed coats from the plants, she noticed something unusual. As she explained, “We had a ton of plants lying around and they had these tiny little seed coats. We noticed a little bit of fuzz in the seed coat. That was our fungus.” That faint fuzz turned out to be the long sought organism scientists had failed to identify for decades.
Hazel was working alongside her faculty mentor Daniel Panaccione when the team realized the significance of what they were seeing. A DNA sample was prepared and sent for genome sequencing, funded through a student research grant. The results confirmed that the organism was a completely new species of fungus, one that had never been formally identified or sequenced before. The genome has since been deposited in a gene bank with Hazel credited for the discovery, marking a rare and remarkable achievement for an undergraduate researcher.
Panaccione emphasized the importance of this step, saying, “Sequencing a genome is a significant thing. It’s amazing for a student.” The fungus was officially named Periglandula clandestina, a reference to how effectively it had remained hidden despite decades of scientific searching. The name reflects both its elusive nature and the quiet persistence of the researchers who finally uncovered it.
Ergot Alkaloids and Their Unusual Origins
Ergot alkaloids are a class of compounds with a complicated reputation. Found most commonly in fungi that grow on grains like rye, they have been responsible for historical poisoning events while also serving as the basis for important medical treatments. What makes them unique is that they are produced exclusively by fungi, never by plants themselves. This fact made the presence of such compounds in morning glories deeply puzzling for researchers.
Morning glory plants live in a symbiotic relationship with Periglandula clandestina. The fungus produces the ergot alkaloids, and the plant distributes them throughout its tissues, particularly into the seeds. This partnership benefits the plant by deterring pests and predators, while the fungus gains a protected environment and steady access to nutrients. As Panaccione explained, “Morning glories contain high concentrations of similar lysergic acid derivatives that give them their psychedelic activities.”
This discovery confirms that the psychoactive properties of morning glories are not a botanical anomaly, but rather the result of a finely tuned biological collaboration. The chemicals long attributed to the plant itself are actually fungal in origin, revealing yet another example of how nature often operates through partnership rather than isolation.
Albert Hofmann’s Long Standing Hypothesis Confirmed
The implications of this finding extend back to the origins of LSD itself. Albert Hofmann, who first synthesized LSD in the late 1930s, was deeply interested in ergot alkaloids and their natural sources. He suspected that the psychoactive compounds found in morning glories were connected to a hidden fungal organism similar to ergot fungus, but neither he nor other scientists of his time were able to locate it.
As Panaccione noted, “This inspired Hofmann and others to investigate morning glories for the presence of a hidden fungus related to the ergot fungus that might be the source of these chemicals. They found very similar chemicals, but they could never find the fungus itself.” The confirmation of Periglandula clandestina closes a scientific loop that remained open for nearly one hundred years.
This moment highlights how scientific understanding can advance slowly, sometimes waiting for new tools, new perspectives, or simply the right person noticing the right detail. Hofmann’s intuition was correct, even if the evidence required another generation to emerge.
Pharmaceutical Potential and Medical Implications
Ergot alkaloids have a long history in medicine despite their risks. In controlled doses, they are used to treat conditions such as migraines, Parkinson’s disease, dementia, and uterine hemorrhaging. LSD itself, a semisynthetic derivative of these compounds, is now being studied for its potential to treat depression, post-traumatic stress disorder, and addiction. The efficiency with which Periglandula clandestina produces these alkaloids makes it especially interesting to pharmaceutical researchers.
Panaccione pointed out the broader implications, stating, “Many things are toxic. But if you administer them in the right dosage or modify them, they can be useful pharmaceuticals.” By studying how this fungus naturally produces large quantities of ergot alkaloids, scientists may discover ways to reduce side effects or develop safer derivatives for therapeutic use.
This research also raises important questions for agriculture and toxicology. Understanding how these compounds are regulated within a symbiotic system could help prevent accidental poisoning while also unlocking new medicinal applications. Nature, once again, appears to have solved problems that modern science is only beginning to understand.
Symbiosis, Intelligence, and the Bigger Picture
Beyond its chemical and medical significance, Periglandula clandestina offers a powerful lesson about symbiosis. The fungus and the morning glory plant function as a single system, each relying on the other to survive and thrive. Neither organism alone produces the outcome that has so deeply influenced human culture and science.
This challenges the tendency to view intelligence and agency as individual traits. Instead, the discovery highlights how complex outcomes often emerge from relationships. Psychedelic compounds, in this context, are not isolated inventions of chemistry but expressions of biological cooperation refined over evolutionary time.
As Hazel reflected on her experience, “I’m lucky to have stumbled into this opportunity. People have been looking for this fungus for years, and one day, I look in the right place, and there it is. I’m very proud of the work that I’ve done at WVU.” Her words capture the essence of this discovery, one that blends patience, curiosity, and humility.
A Quiet Milestone in Science and Consciousness
The sequencing of Periglandula clandestina represents more than the identification of a new species. It confirms long held scientific theories, opens new paths for medicine, and deepens our understanding of how consciousness altering compounds arise in nature. It also reminds us that some of the most influential forces shaping human experience originate in relationships so small they can be overlooked for generations.
Hidden within a seed coat, this fungus quietly bridged plant biology, human chemistry, and the future of mental health research. Its discovery suggests that many of nature’s most powerful tools are still waiting to be recognized, not through force or conquest, but through careful observation and respect for the systems already in place.
As science continues to explore the boundaries of mind, medicine, and meaning, this discovery stands as a reminder that answers often grow slowly, invisibly, and in partnership with life itself.
