coral ID

Hi all, I don't have a camera so I'll do my best to describe it. I have several pieces on my aquacultured live rock. To keep it simple, the have a bone colored "stalk" (not sure proper terminology) kind of growing like a tree branch, about 3 mm wide, and up to 1 cm long, with one single pink polyp about the size of a pea on the end of each one. Any ideas?
 
I've looked for pics, and can't find anything. :confused: I can't think of anymore info., they're really as simple looking as I described. If anyone has specific questions they want to ask, I'll answer them the best I can.
