I would guess based on that description calcerous green algae, but would have to see a picture to know for sure. If thats what it is, its a nice plant doesn't grow out of control, but uses calcium ~ good or bad? Up to you. Personally I like them.
with out a picture and or better description its not going to be easy to tell you good, bad, or indifferent. a flat plant growing on a rock can be anything from a macro algae, coraline, or even the start of a coral.
