Psilocybe mexicana, often called the “Mexican liberty cap,” is a bundle of tightly packed mycelium that can range in size from smaller than a pea to as large as an ostrich egg.
The color of the sclerotia appears to depend on the growing conditions and can range from a light yellow to a dark brown or even a blue hue in certain areas. Since they have irregular shapes, sizes, and colors, it can be difficult to identify them based on their sclerotia alone.
Experience: It has been said the Mexican liberty caps can bring visual hallucinations and heighten overall moods, bringing on euphoria and happiness. Some have also said to feel giggly or laugh a lot when consuming them.
