I realize this is kind of a strange thing to ask, but I need to know if it's likely for a store bought pizza to contain the mushrooms that the pizza did in the video (Ink Cap Mushrooms).

I'd most like to know today, as I ate a pizza with mushrooms yesterday, and the box didn't say what they were, and I'd like to know because you have to wait 4-5 days or something before you drink alcohol. Does anyone here know if it's likely for a store bought pizza to contain these, I'd really like to know soon (very soon if possible, I plan on drinking tonight).
