mushroom hard coral
seen? This plate-like coral that is stuck to a hard surface
is rarely seen. It was seen once at Cyrene Reef.
Features: Flat plate-like about
20cm in diameter, attached at the base but wavy with lobes at the
edges. May also be encrusting. The corallites form a distinctive pattern
of thick parallel lines perpendicular to the edge. There is a 'waist'
in the parallel lines at the mouth of the corallite, i.e., the parallel
lines merge at regular intervals. The walls are thick with fine 'teeth'.
May be confused with Bracket mushroom coral
(Podabacia sp.) which has finer lines with thinner walls.
Status and threats: It is listed
as globally Near Threatened by
Cyrene Reef, Mar 07
