Is it sps or lps??? Never seen or heard of it before!

Looks kind of like a favia/chalice to me.

EDIT: Woops googled the wrong spelling, i just saw it on DD, i would say it is an LPS.

Its an SPS, its also spelled Astreopora. It looks like an LPS because the scale of the photo is deceiving. The corallites are only about 3 or 4 mm in diameter. The photo above is a close-up.
