Asparagus Pot Weird Asparagus Thing Growing In Pot?

Weird asparagus thing growing in pot? - asparagus pot

I have my planter in the garage, and I noticed the pink thing will die from the ground near one of the plants. I took it out and it seemed just the tip of the asparagus, but thicker and pink. I saw a few tricks sticks and digging and found a small group of these things always on the floor. What the hell is that? He was afraid, because it seemed very strange and I have it there. Is that a type of asparagus or mushrooms?
