Found odd white things on base of coral and frag plug

[Emi2852]

When my Torch coral closed up for the night I noticed some odd white growths. (Not the white curly worms... I don’t know their name) but I’m wondering about the larger white tube like things. Sorry for the quality my phone refused to focus on the plug. Does anyone know what these are and if they are dangerous the my torch and other corals in the tank?
