I am still a bit new to the mushroom world, is this a Yuma? For some context here a lot of Japanese sites just broadly list what looks like Discos, Yumas and Rhodactis under a broad category of "Disc Coral" Which I assume is shorthand for the family name but they're also excluded from any filters for mushroom corals. Anyways before I ramble, much appreciated to whomever helps me continue growing my index!
