Psilofyr was viewed by the myconids as a deific mediator and teacher who taught their earliest ancestors the secrets of potion-brewing.
Psilofyr was typically depicted as a fungal version of a world tree, with its mycelia reaching across the planes of existence from its home in Nirvana, to connect with all myconid communities.
Psilofyr's foremost concern was the protection of the myconid race, as well as the pursuit of philosophical perfection.
The deity's avatar appeared in the shape of an enormous myconid with a massive mycelium complex drifting about behind it as it moved through levitation. The colour of Psilofyr's avatar was said to change to fit its mood, though grayish blue was the most common appearance.
