are thin laminae arranged in whorls or tiers or, rarely, forming tubes.
Stands over 5 metres across are not unusual. Corallites are relatively
thin walled and small (2.5-4 mm diameter). Columellae are small and
compact, and paliform lobes are well developed.

Echinopora lamellosa. E costata has larger corallites, horizontal plates,
and the radiating ridges go right through corallites near the edge of the
plate, rather unbelievable. I found it in Indonesia, not sure anybody else
has seen it yet. The only pictures Veron has on www.coralsoftheworld.org are
the ones I took. Only saw it at one dive spot, got sample, got the species
named. Never seen it again but I haven't been back to Indonesia. Indonesia
is a a bigger place than most people realize, because those stupid flat maps
everyone likes to use (Mercator projection) hugely distort the world, making
Greenland look hugeer than it is and Indonesia small. Indonesia is longest
east-west,and north-south at one point it is as far as London to St.
Petersburg, Russia. /Douglas Fenner via FB
Oxypora lacera (Verrill 1864) Scroll or Chalice Coral. Composed
of thin lamina, scroll-like, that may be greatly thickened in areas of
substantial water movement. Costae toothed (differentiating
characteristic). Close up pic by DiF in the Red Sea.
