I wonder if there exists people who aggressively believe mushrooms are plants, similar to people who defend Pluto as a planet.

The International Astronomical Union (IAU) defined in August 2006 that, in the Solar System, a planet is a celestial body that:

is in orbit around the Sun,

has sufficient mass to assume hydrostatic equilibrium (a nearly round shape), and

has “cleared the neighbourhood” around its orbit.

And in that same article:

It has been argued that the definition is problematic because it depends on the location of the body: if a Mars-sized body were discovered in the inner Oort cloud, it would not have enough mass to clear out a neighbourhood that size and meet criterion 3. The requirement for hydrostatic equilibrium (criterion 2) is also universally treated loosely as simply a requirement for roundedness; Mercury is not actually in hydrostatic equilibrium, but is explicitly included by the IAU definition as a planet
