I’d say it is, and it’s a gorgeous coral too!Recently won an auction for a diaseris plate coral and curious if anyone can confirm it is a diaseris?
The last diaseris plate I had looked different and didn’t have such a defined mouth
The vendor sent pics showing and saying that he crave the plates I bought all the time and says they are more definitely diaseris I’m definitely no expertYour coral is actually a Heliofungia fralinae:
Your coral has thick, clubbed tentacles with purple acrospheres, which is a defining characteristic of this species when infated.
True Diaseris are blob-like plates like this:
Also, Diaseris not a valid genus as it was synonymized with Cycloseris.
I wouldn't trust vendor IDs ( even reputable vendors), especially with LPS corals, as they are prone to not using up-to-date taxonomy or misidentifying corals, like in this case.
Like I said, vendors misidentify corals all the time so I wouldn't trust their IDs. Just because your vendor cut the plates doesn't mean that it is Diaseris. Many solitary plates corals can be cut and heal properly. Diaseris will self-fragentate without the need of someone cutting them, and do not have a regular circular shape, but instead a blobby shape like the photos shown. Also, remember that Diaseris is a synonym of Cycloseris, which means that all Diaseris are actually Cycloseris species.
