Okay so you know the top part of a parasect, well say you find one in battle and you kill it, you could use the top shell thing of put a stick under it and have an Umbrella! i think it's a good idea, but tell me your own opinions.
It's a mushroom, and therefore, would naturally decay over time. Therefore it wouldn't be a suitable umbrella. Plus why use it for that when you can use it for other reasons?
I Don't know I was bored one day
