Ricordia or Yuma?

[fish590a]

How can I tell the diff. between Ricordia & Yuma? I have this colony that was sold to me as Ricordia but I was told it was Yuma.
Here's a couple pics, sorry I could not capture the real color, it is green and pink base.





also are these rare?

Not sure about the rarity.

Those are Ricordia Yuma. Note the bumps around the mouth.

There is also Ricordia Florida. Lacking bumps on the mouth.
