Great picture. However, I am 100% sure that the "unknown" is not a echinata or a lord. Someone with the "unknown" just needs to test the theory.
I had to read this post over a few times, and I'm not completely sure I know what your saying, but if you are saying that the piece you are calling A. maxima is defiantly not a lord or echinata, I would agree with you. What ever they are, they are something else.
For example, the orange looking coral at The Captive Reef looks like an orange Scolymia vitensis.
Here's a link to his Orange coral.

It could be Multi-mouth Scolymia vitiensis
Maybe a multi-mouth Scolymia australis
Characters: Usually solitary but sometimes two to four centres occur in one corallite, or occasionally in separate corallites. Corallites are saucer-shaped and less than 60 millimetres diameter. Septa are sturdy with blunt saw-like teeth.
Or possibly Scolymia cubensis
Characters: Usually attached but may be free-living, with a tapered base. Polyps have one, rarely two or more centres and are sometimes over 100 millimetres across. They may be only a few millimetres thick, with successive regrowths forming tiers. Sometimes corallites have several mouths. Septa are in two or three orders of slightly different size. A paliform crown may be distinguishable. Polyps are fleshy. Colour: Uniform or variegated brown, red, tan or green. Sometimes bright orange (which may photograph brown). Similar species: Solitary polyps of Mussa angulosa. Habitat: Lower reef slopes and soft substrates. Abundance: Uncommon.
Taxonomic note: It is commonly believed that there are three, not one, species of Scolymia in the Atlantic. The names Scolymia lacera (Pallas, 1766), S. cubensis (Milne Edwards & Haime, 1849) and S. wellsi (Laborel, 1967) have been variously used. In most publications (best depicted by Zlatarski and Estalella, 1982), S. lacera is actually Mussa angulosa with solitary polyps. The name S. wellsi is usually given to small polyps of the present species and to those from Brazil. Source reference: Veron (2000). Taxonomic reference: Fenner (1993).
