What species of cup corals?

Anyone know what species of cup corals these are? They are from 2 different sites in the Mergui Archipelago, Myanmar.

There are a few potential matches including Tubastrea sp. and Dendrophyllia sp..

Without being able to see the skeleton, the best you can say is they are from family Dendrophylliidae. They could be either Tubastraea or Dendrophyllia.

Thanks Andrew.
