Apiophragma Hayward & Ryland 1993
Genus Apiophragma Hayward & Ryland, 1993 Revised diagnosis. Colony encrusting, small, spot-like. Autozooids arranged contiguously in quincunx, communicating via basal pore-chambers. Gymnocyst continuous around zooid, narrow to moderately well developed. Cryptocyst and opesia surrounded by a dist...
