Amanita Muscaria is actually a completely different species from Psilocybe Cubensis, and contains a different active ingredient (muscimol as opposed to psilocybin in cubensis mushrooms). Amanita Muscaria is also a toxic mushroom, and can be deadly if too much is ingested so dosage is extremely important with this species of psychedelic mushroom.
Despite its toxicity there is a long history of use in several indigenous cultures (like the Inuit and Siberian Indigenous peoples) likely due to the dissassociative effects (meaning many of your senses are dulled) of the active compound allowing them to endure harsh conditions. Its also documented that other species of animal (like reindeer) seek out and enjoy eating amanita's, and there is even a (rather far-fetched) theory that the legend of Santa Claus was derived from the Indigenous Shamans who would dress in red and collect Amanita's from under pine trees (where they commonly grow).
As for the experience elicited by Amanita Muscaria mushrooms I (Jeff) cannot comment as I have never had the privilege of the experience. According to online forums/communities such as reddit and shroomery it is typically a less enjoyable experience than psilocybin, often accompanied with physical side effects like sweating, confusion, vomiting, and gastrointestinal discomfort.
For more information on what an Amanita experience is like I would encourage you to check out the Amanita section of the forum "shroomery" and also the r/psychonaut subreddit!
