Almost nobody uses Shroomish in battle. It exists to evolve into Breloom, which is a completely different story. Get it there and you won't regret it. Been around since Gen 3. 5 type weaknesses to keep in mind.
Shroomish's stats barely vary. 0 sit in respectable range with no real gaps. It's a blank slate for EV investment. Worth 1 HP EV, standard growth curve to max.
It prefers damp places. By day it remains still in the forest shade. It releases toxic powder from its head.
If it senses danger, it scatters spores from the top of its head to protect itself.
Shroomish Weakness
FragileFire, Ice, Poison, Flying, and Bug-type moves hit Shroomish for super-effective damage. It resists 4 types, giving it decent defensive coverage.

Shroomish isn't fully evolved, so it's not built for competitive play. You'll want to evolve it into Breloom to unlock its full potential. At 295 BST, it's a stepping stone rather than a team anchor.
Watch for Charizard (Fire), Cloyster (Ice), and Crobat (Poison) when using Shroomish. They all hit it super-effectively with STAB. Flying and Bug-type attackers are also a problem. With 5 weakness types, most competitive teams carry at least one counter. At base 35 Speed, Shroomish won't outrun any of these threats so switching to a resist is usually the safer play.
Shroomish evolves into Breloom at level 23. Shroomish is the base form of this evolutionary line.
Run Poison Heal on Shroomish. It's the ability that defines how you build around it and the main reason it holds a competitive niche. Shroomish also gets Effect Spore and Quick Feet, but they don't compare.
Shroomish fills the balanced role. It's a physical attacker with base 40 Attack. Base 35 Speed is low. Priority moves or Trick Room are the way to go.
