Soft, has a stalk coral?

[Lyvric]

Has little nubs on top when happy. yellow in color most of the time, but sometimes has patches of green. has small nubs with barely sand teeny lashes. Maybe a baby toadstool with no fingers? Just started to grow on a chunk of live-rock one day and I left it alone. Sorry for the bad pic, my phone isn't the greatest.

cant tell anything from the picture, but from what you describe my bet would be a toadstool

has to be some type of leather from the way you are describing it. Maybe a devils hand coral?
