What are the mushrooms that produce hallucinations?

There are several species of mushrooms that contain psilocybin, a naturally occurring psychedelic compound that can produce hallucinations. These mushrooms are commonly referred to as "magic mushrooms" or "shrooms." Some well-known species that contain psilocybin include:

1. Psilocybe cubensis: This is one of the most commonly known and widely distributed psilocybin mushrooms. It is found in tropical and subtropical regions around the world, including Mexico, Central and South America, Southeast Asia, and the southern United States.

2. Panaeolus cyanescens: Also known as the "blue meanie," this psilocybin mushroom is found in temperate regions of North America and Europe. It typically grows in grassy areas, such as parks, lawns, and pastures.

3. Psilocybe semilanceata: Commonly called the "liberty cap," this mushroom is native to Europe, but has been introduced to other parts of the world, including North America and New Zealand. It is found in grassy areas, such as meadows, fields, and roadside verges.

4. Gymnopilus junonius: This mushroom is found in North America, Europe, and Asia. It typically grows in clusters on or around decaying tree stumps and logs.

It's important to note that psilocybin mushrooms are illegal to possess, use, or sell in many countries and regions. They can have significant effects on perception, mood, and behavior, and should be used with caution and only in controlled settings under the supervision of trained professionals.
