Sure, here are three limericks about mushrooms that might bring a smile to your face:

1. There once was a mushroom so stout,
It refused to be tossed about.
It said with a grin,
"I won't let you win,
I'll cling to this log like a sprout!"

2. A mushroom named Freddy the Fungus,
Had a hairstyle that was quite wondrous.
His cap was so neat,
It looked like a treat,
And his stem was incredibly humongous!

3. There once was a mushroom so grand,
It sprouted up from the land.
But try as it might,
It just couldn't get light,
So it waved at the roots with its hand!
