Psilocybin ceremony
There are several variations possible within psilocybin ceremonies. Psilocybin can be obtained from truffles or magic mushrooms. Therefore, the use of truffles is referred to as a truffle ceremony, while the use of magic mushrooms is called a mushroom ceremony. A more recent development is the addition of strong MAO inhibitors to the mushrooms or truffles, which is then called psilohuasca. Adding a milder MAO inhibitor, such as passionflower, is safer compared to psilohuasca, and this is called psiloflora.
As you can see, there is quite a lot to choose from. You can find more explanation about the various terms via the following links:
