* '''Daemon webcap''': Known in real life as the Goliath webcap. The name in the Mazes is a reference to the Daemon, a Demonic creature.
* '''Demonic mushroom''': Known in real life as Satan's mushroom. The name in the Mazes is a simple reference to the Demonic faction.
* '''Nisekan''': Known in real life as Caesar's Mushroom. The name in the Mazes is a Youkai-go language reference to the mushroom's shape and appearance. 偽柑 (nisekan) is transliterated to "fake orange" or "fake citrus", so called because this mushroom can be confused for an orange.
* '''Oni's Bane''': Known in real life as the ''tippler's bane'', the ''ink cap'' or ''inky cap'', this mushroom was given this name because, much like in real life, it becomes poisonous when consumed with alcohol.
** Oni have vilified black mushrooms to the point of using "black mushroom" as a synonym for "toxic" or "hazardous". This is because both the ''Oni's Bane'' and the magic ''Oni terror'', which induce Anti-Oni Syndrome, are black in color.
