CAULIFLOWER MUSHROOM?

 
Bloomfield, CT - This mushroom has been growing in back of our office for the last week or so. It is quite a distance from the building so we were not quite sure what it was, originally we thought it was a McDonalds bag because it is quite large about a foot across. So yesterday we went out to investigate and this is what we saw. It looks like Coral to me but when I looked it up it resembles a Cauliflower Mushroom more. If there are any people in the know, let me know what it is.
