Look like regular acan lords to me, and nice ones at that.
Acanastrea Lordhowensis.
Micromussa's are generally smaller than lords, and echinata doesn't have single polyps that come out of the skeleton like the lords do. You really can't tell the specific on acans until you take a skeleton and start measuring. There are micro's and lords that are similar size and some acan lords that don't protrude as much sometimes looking like echinata's. People just kinda group each by size and features.
Unless your asking for the collectors names for the color patterns that you have. If so, just make something up and start telling everyone that. It'll catch on and one day you will have a "LE PeteTheGeek Electric Dogfart Acan" or something silly on the market selling for big bucks.
