I've be very happy to send you photos of the Hawaiian rice coral Montipora dilatata Studer 1903. Please note that I consider other species named by Veron as M. turgescens in Hawaii to also be M. dilatata.
The type locality for M. turgescens named and described by Bernard was collected at the Great Barrier Reef. Given that the GBR is 8,000 km from Hawaii, there is virtually no chance for the species same as named M. turgescens reported in Hawaii to be the same as that at the GBR. As a result, I consider all corals called M. dilatata or M. turgescens collected in Hawaii to all be Montipora dilatata Studer 1903.
Genetic analysis for M. turgescens should be based on specimens collected at its type locality (Great Barrier Reef) and not just from Hawaii.
I have attached photos of the species alive and underwater at Kaneohe Bay, Oahu, Hawaii (OAH), Palmyra Atoll, Line Islands (PAL, and other photos of the species photographed at four of the Northwestern Hawaiian Islands: Pearl and Hermes Atoll (P&H), Lisianski Island (LIS), Kure Atoll (KUR), and Midway Atoll MID).
Sincerely, James E. Maragos, Ph.D., [ret.]
