White worm is a type of monster in ADOM. They are notable for being breeders — meaning that if the PC leaves one or more untouched for too long (especially if (s)he is resting for a while to regain HP), they can grow in number exponentially. If this occurs in the Small Cave, early game PCs may face a baffling and frustrating death by being torn apart by very strong worms. White worms have no other special powers.
