Echinopora lamellosa (Esper 1791). /COTW:
Characters: Colonies
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.
Colour: Amber,
pale to dark brown or greenish, often with darker brown or green
calices.
Similar
Species: Echinopora
ashmorensis, E.
pacificus and E.
gemmacea.
Habitat: May
be a dominant species in shallow water habitats with flat substrates.
Abundance: Common.
Taxonomic Note: A species complex.

Leptoseris explanata Yabe & Sugiyama 1941. Colonies made up of
one-sided blades. Corallites expand as they grow toward end of blades.
/COTW:
Characters: Colonies
are composed of unifacial laminae which may be horizontal with entire or
lobed margins, or contorted and partly upright. Corallites are widely
spaced and outwardly inclined. Long and short septo-costae alternate
strongly and form fine but conspicuous radiating striations.
Colour: Pale
brown or yellow-brown, often with white margins.
Similar
Species: Leptoseris
gardineri and L.
scabra.
Habitat: Usually
found on vertical or overhung faces, especially of lower reef slopes.
Abundance: Uncommon.

Leptoseris mycetoseroides Wells 1954, /COTW:
Characters: Colonies
are encrusting or laminar plates which frequently exceed one metre across.
Plates have small irregular folds on the surface. Corallites are crowded
between the folds except towards the periphery where they are aligned in
rows parallel to the margins. They are outwardly inclined. Septo-costae are
fine and even.
Colour: Mottled
brown and green, usually dark colours if shaded.
Similar Species: Leptoseris
foliosa, which is distinguished by its smooth surface and rounded
corallite openings. See also L.
yabei and Pavona
varians.
Habitat: Reef
slopes protected from wave action, especially steeply sloping or vertical
walls.
Abundance: Sometimes
common. NSUL
