Thank you so much to the both of you!!

I've never foraged a mushroom before, but feel like this is either Laetiporus cincinatus or Laetiporus sulphureus. Can anyone help confirm my suspicion? Found on the ground on the base of an oak tree that had seen better days but was still alive towards the top. I live in Massachusetts. It feels damp to the touch and is roughly 10inches across and weighs about 3-5 lbs.
