What are the most potent magic mushrooms?

While there are literally hundreds of species of fungi that produce psychedelic mushrooms, some are far more potent than others. Certain species produce higher concentrations of the psychoactive alkaolids Psilocin, Psilocybin, and Baeocystin. These three compounds are reported to have synergistic psychedelic effects.

The top three potent magic mushrooms as ranked in Paul Stamet’s book, Psilocybin Mushrooms of the World, are as follows:

  1. P. azurenscens
  2. P. bohemica
  3. P. semilanceata

While these are the top 3 magic mushrooms in potency, they are not very common varieties. In other words, you may be hard pressed to find a dried sack of any of these mushrooms. This is primarily due to the species’ ease of growth and adoption by cultivators.

That said, another question may be, what are the most potent common magic mushrooms?

The most potent commonly found mushrooms are as follows:

  1. P. cyanescens (wavycaps)
  2. P. tampanensis
  3. P. cubensis

Below you will find the full magic mushroom potency chart based on the percentage of psychoactive compounds found within each of the most common species.
