Some type of macro algae?

I think this came along with my ricordia (sp?). Didn't notice it until 2 days ago, even though the Ric. has been in the tank about 3 weeks. Whatever it is seems to be growing pretty fast. Any ideas?

(ps. I never realized the depth of that ricordia until I took this macro shot)
