Possible red algae, Not sure, need help on id'ing

[bernacchi]

Right up under a red mushroom, there is a feathery red something growing. We're not sure if it is an algae or what. It's growing outward and a beautiful deep red color and feathery. I need help in identifying. Is it a good thing or not?
