If it's hard and encrusting then it is a type of coralline algae. If you touch it, is it soft or hard?

Hand and crunchy like coralline

Then it is coralline! I had it in a hermit shell for a week and one day it disappeared. So I'm not actually sure if it can survive long term like regular coralline.
