I've removed it with a mold remover spray. We live in the UK and it's meant to be my daughter's bedroom but I don't feel comfortable with this at all. Thank you
Found in northern Wisconsin. My father says it's Witch's Butter, but I have big doubts.
What about it?
We have been camping for the past week, and this buddy popped up over the past two days. It looks significantly larger today than it did yesterday when I first noticed it.
