Psilofyr, the benevolent myconid Power, is a meditator-patron dwelling in Nirvana. He is a teacher Power, one who taught the first myconids the secrets of potion-making through direct revelation. He is often depicted as a type of fungal world-tree, his mycelia reaching down through the planes into the home of the myconid-King. Psilofyr's only concerns are the protection of the myconid race and the pursuit of perfection through meditation.

Psilofyr selects about one myconid king in 20 to become a cleric, and always guides myconids in their selection of a new king through intuitive guidance. Psilofyr has no need of omens since he constantly shares thoughts with his kings.
