A Raging Mushroom is fed to a man and it causes him to become aggressively horny, only thinking about pinning down and raping the closest unmarried monstergirl. This also has the effect of weakening or mitigating the inherent strength that most monster girls have. However, this only works if said monster girl desires to be pinned down and raped.

Now, a Pseudo-Matango Mushroom is fed to monster girls, even humans. They start thinking about sex and other lewd things, and it gets to the point where the only thing they can think about is filling their womb with a large mushroom (read; penis).
