Granulosa and Loripes are the two toughest acros to tell apart that are available on the market today. The best way that I can distinguish between them is in the new growth. The Granulosa will grow in more of a clump and the Loripes will grow more spread out. Both species have similar Radial and Axial corallites.
I agree that it looks like a Granulosa over Loripes but I'm not 100% sure.
