Red Macro?

[psa]

I've been trying to identify this for some time and wondered if anyone could help me out. It grew from nothing on a piece of live rock over the last five months and is quite nice looking, I believe. I have no tangs or anything that would eat macro so I have no idea about its edibility, but I hoped someone would recognize it or point me in the right direction.

This one was taken about a month ago(saturation is a bit high on the picture here):

And this one was taken today (very true to actual color):

try searching under rhodophyta.
