Mycelium Growth and Development of Psilocybe spp. Mother Cultures on Agar-Based Media

The resurgence of interest in the therapeutic potential of psilocybin-producing mushrooms has recently led to numerous research and commercialization efforts. Due to its ease of cultivation and high potency, Psilocybe is the primary genus of interest, and there is a growing need to standardize maintenance, proliferation, and cultivation techniques for efficient and consistent production. The investigation of mycelial growth and development on agar-based media is of principal importance to regulate and optimize mycelium growth and preservation protocols for subsequent fruiting body development. The current investigation is the first to examine the mycelial growth and morphology of four Psilocybe genotypes cultured on different agar-based media. The results from this simple set of experiments provides the foundation for future optimization studies. Ultimately, the information presented can be used to develop genotype-specific mycelial growth and development practices that will shape the future of psychedelic mushroom production for clinical and industrial applications.
