Yellow-gilled Gymnopilus

These mushrooms are pretty dangerous. I heard eating them gives you an amazing feeling. And eventually it will kill you. I am growing them because some humans pay good money for them. I guess they aren't as dangerous for them.
— A dryad
A psilocybin mushroom which is mostly present on the east and west coast of North America. It has a very bitter taste and no toxity. The mushroom is highly addictive to dryads. A few farmers cultivate these mushrooms in small quantities, but most just gather them from their natural habitats.  

Cultural Significance

The yellow gilled gymnopilus is one of the most infamous mushrooms in the Northeastern American dryad communities. It has killed many young dryads over the years. Some humans distribute them to combat dryad communities without attacking them directly.   Today growing or collecting this mushroom is illegal in New York and in many other places. Despite this, some dryads and humans have grown them in small quantities to sell to humans as they are exploring the effects of psilocybin. The Dryad Wilderness Federation of the Adirondack Mountains actively fight to wipe out this mushroom, but spores are easy to hide and regrow.

Alchemical Use

Alchemists use this mushroom as an ingredient for potions with effects on mental health both in a healing and harmful way. The creation of these potions is highly controversial. The North American Society of Alchemists advises against their use in general, but supports some research into potential beneficial uses.   Only a handful of people know how to create a highly concentrated psilocybin pastes, oils and elixirs in a highly complex alchemist process.

    I didn't know about this one and found the detailed description very interesting — it's fantastic for better immersion, and WBtV mixes reality with fantasy nicely.   I noticed that it is denoted as slightly bitter in the introduction, while the description in the sidebar says that it is very bitter. Is this a difference in dryad vs human taste perception or a typo? :P

    Oooo another mushroom, and a magic one at that. I'm happy to see psilocybin mentioned. It's making some waves nowadays. The description is very well done and I really liked how you include some history with the dryads. To top it off, its a real shroom! Not only a good a read, I got to learn something! Well done.

    'Some humans distribute them to combat dryad communities without attacking them directly.' Rude.   I always love when you take things that are real and give them a twist for your world. You did a great job with the description here, too! :D
