I have a piece of live lock that currently what looks like short grass or moss, is this hair algae? It is only on on piece of rock.

Does it look like blades of grass or are they filamentous? If it's filamentous looking, then it's probably hair algae, if it looks like blades of grass its probably some beneficial macro algae.
