Myconid adults were the primary workers and defenders of Fungusfolk communities, typically between eight and twelve years of age. At this stage, they were fully mobile and capable of reproducing through spores, contributing directly to the growth and maintenance of their colonies. Adults performed essential tasks such as agriculture, construction, exploration, and scavenging for nutrients or corpses to be used as fertilizer or animated by the Myconid Sovereigns.
In the event of danger, adults could defend the colony alongside elders, often coordinating with other members using distress or pacifying spores. They were experienced enough to participate in melding rituals, though their responsibilities were focused more on practical work and colony stability than leadership or advanced spore Spellcraft.
