What type of chalice is this chalice?

[MoshJosh]

The only chalices I can pretty consistently ID are the mycedium chalices. . . everything after that I pretty much draw a blank. What is the scientific/species name for these?

Also. . . a crab pushed that purple non-mycedium chalice (the purply one on the left ^^^) into my space invader mycedium chalice. . . WRECKING IT!

Any chalice experts out there that can help me out?
