yumas are ricordias as far as I understand. To my knowledge the distinction is between Yuma and Florida. These are Yuma I think but mushroom connoisseurs will be around soon to let us know
They are riccordea, riccordea is a genus. There are two species of riccordea typically kept Riccordea Florida and Riccordea Yuma. That looks like a florida to me, but I could be wrong. Floridas grow faster and require less light and flow than Yumas.
