The Monster Manual says:
A spore servant is any Large or smaller creature brought back to life by the animating spores of a myconid sovereign. A creature that was never flesh and blood to begin with (such as a construct, elemental, ooze, plant, or undead) can't be turned into a spore servant.
—Spore Servant Template, Monster Manual, pg. 230
Animating Spores (3/Day). The myconid targets one corpse of a humanoid or a Large or smaller beast within 5 feet of it and releases spores at the corpse. In 24 hours, the corpse rises as a spore servant.
—Myconid Sovereign, Monster Manual, pg. 231
Which of these contradictory conditions are correct here?
