This is one of the strangest looking chalices we have. Being a light blue/yellow colour it is very striking under both blue or white light.
Under the right conditions the base colour is light yellow/blue and the oral discs are yellow, the growth rim will glow light yellow . With really good conditions the growth perimeter glows bright fluorescent yellow. Quite a spooky prospect!
this chalice will take reasonably high light, but prefers medium flow and medium to low light. the second photo is of one of our mother colonies. Frags are mounted on medium plugs and are extremely well grown out.. nearly the size of a small colony.
