There is something significantly different between these corals....the tissue in some has that varible texture on some (like mine) and some have that lobo-like smoothness. The pics I am seeing in Vernon are a closer match to the former. But we all know that you cant really ID a coral via just its tissue color/shape/expansion/texture etc. Its the skeleton that is usually diagnostic.
So anyway, if the "unknowns" are not really wilsoni, what are they? I have dog-eared my references and havent seen anything else that fits the description.
