Id these 2 things please.

[reefwithareefer]

These 2 things started growing in my tank about 2/3 weeks ago. I have not been able to find anything similar from google etc.
I am hoping to ID them , so that I know if I need to get rid of them or not.

The "mushroom" looking thing is growing in a"swirl" , it is soft/rubbery to the touch. It is about 1/2" round.

The other pic is of some sort of green plant.

Sorry for the poor quality pics. I only have a phone cam.
