Trivia[ | ]

  • Mucormycosis originates from the Antibirth mod. In Antibirth, this item would create a poison fart cloud on every kill, similar to Collectible Contagion iconContagion. The Mucormycosis fart clouds could also knock Isaac away and potentially into hazards.
  • Mucormycosis is a fungal infection caused by fungi in the order Mucorales.
