PT 645 - Oli Genn-Bash: Functional Mushrooms, Hype Cycles, and Mycelial Thinking

Oli Genn-Bash (Brighton, UK) joins Joe Moore for a grounded conversation on the boom in functional mushrooms and why the category may be moving too quickly. As the founder of The Fungi Consultant, Oli works with consumers and brands to demystify functional mushrooms, with a focus on education, traceability, and realistic expectations.

The conversation begins with a critique of wellness hype cycles. Oli explains how consumer desperation for help with anxiety, sleep, stress, and cognition can create an opening for a rapid wave of products that are not always grounded in careful sourcing or clear science. Using lion’s mane as a case study, he contrasts popular cognitive claims with traditional use, arguing that the most useful path forward is to slow down, get more literate about mechanisms, and build a market that can sustain trust over time.

Systems and Culture

Oli describes how individual health is inseparable from community realities, including food access, class dynamics, and what wellness advice can sound like when it lands from a place of privilege. They discuss mycelial thinking as a practical framework for collaboration and resource-sharing, and why mushrooms tend to attract unusually generous “teach everyone” communities.

They also explore the role of mushrooms in meaning-making and consciousness. Oli shares personal reflections on mushrooms as allies, the felt sense of “agency” in psychedelic experiences, and how those experiences can encourage behavioral change without forcing it. The conversation touches on alcohol culture in the UK and the possibility of non-alcoholic alternatives, including how functional mushrooms, microdosing, and other botanicals can support social confidence and energy for some people.

Finally, they look ahead at fungal innovation beyond supplements: materials, soil health, regenerative approaches, bioremediation, and what the broader psychedelic movement might learn from fungi’s patience, symbiosis, and balance.

Key themes and takeaways

1) Why functional mushrooms feel “too fast” right now

Oli argues that functional mushrooms have accelerated into a high-pressure wellness marketplace, with brands rushing products to market and consumers struggling to determine what is legitimate, traceable, and effective. He draws parallels to the UK CBD market, describing how oversaturation and inconsistent quality can erode trust and collapse prices.

2) Lion’s mane, tradition, and mechanism

Lion’s mane is a useful example of how modern marketing can outrun nuance. Oli notes the gap between popular cognitive claims and traditional use, and points toward the gut-brain axis as one plausible bridge that requires more careful explanation and patience.

3) “Functional mushrooms” as a frame

Oli prefers the term functional mushrooms over medicinal mushrooms, emphasizing systems-level support rather than a pharmaceutical model. He describes a view of health that starts on the cellular level and asks what supports function, resilience, and prevention.

4) Health is individual and collective

Oli speaks candidly about barriers to wellness in the UK, including food poverty, access to education about cooking, and how class dynamics shape what health messaging sounds like. The broader point is structural: it is difficult to talk about supplements without considering the baseline conditions of daily life.

5) Mycelial thinking, futures work, and collaboration

The conversation highlights “mycelial thinking” as more than a metaphor. Oli describes collaborations in futures-oriented communities and how fungal logic can inform collaboration, non-zero-sum outcomes, and resource sharing.

6) Mushroom culture and the instinct to share

Joe notes how strikingly generous mushroom communities can be, especially around cultivation and identification. Oli agrees and adds a provocative angle: the possibility of “agency” in fungi and a sense that mushrooms invite humans into relationship, curiosity, and participation.

7) Alcohol culture and alternatives

Oli reflects on nearly three years without alcohol and describes how functional mushrooms and other botanicals can support mood, energy, and social confidence for some people. They also discuss the realities of events culture, including the need for more inclusive non-alcoholic options and sensitivity to addiction histories.

8) The next 10 years of fungi

They look at the expansion of fungi into materials, fashion, regenerative agriculture, soil health, and bioremediation. Oli emphasizes balance: fungal innovations are promising, but scaling and real-world constraints matter.

9) What the psychedelic movement can learn from fungi

Oli critiques extractive, capital-driven dynamics in the psychedelic ecosystem and suggests fungi offer a different ethic: patience, humility, symbiosis, and realism about parasitism and imbalance.
