After reading what Marie wrote I did a search and can definitely see what you mean about the rics mouth differences. I bought those rics last night from a LFS but never even asked if they were rics or not, I just assumed they were(they can't be just normal mushrooms right?). I got 6 of them on one rock, all are a slightly different color for $40
I also discovered that Yumas will reproduce via leaving a piece of the foot behind when it moves(which my orange has done a couple times) and a Florida will split once it's large enough.
