Rics, Florida or Yuma?

[noirsphynx]

Does anyone know how to tell the difference between Florida Ricordia & Yuma Ricordea? Here's some pics of my rics & other mushrooms and any help identifying what type they are would be great. I have several labelled as rics but that's just an assumption, they weren't labelled in the store.
