Description. Blastomussa merleti forms phaceloid colonies by extra-tentacular budding ( Fig. 1A View Fig ). Corallites are regularly spaced. Corallites are round to oval and 5–7 mm in largest diameter ( Figs. 1A, C View Fig , 7A View Fig ). Three cycles of septa are present, the first two reach the columella and are equal or sub-equal as the first can be slightly thicker and more exsert ( Figs. 1B, C View Fig ). The third is reduced to less than 1 / 2 to 1 / 3 of the length of the first two ( Fig. 1C View Fig ). Septa are composed of one to three fan systems thus attaining smooth to dentate margins ( Fig. 1B View Fig ) ( Chevalier, 1975: Fig. 204). Septal margins and sides finely granulated. Columella formed by trabecular processes from the inner margins of septa and by round papillae in the center. The papillae can be separated or fused to form a sublamellar structure in the middle of the columella ( Figs. 1A, C View Fig , 7A View Fig ) which gives it a quasi-bilateral symmetry (see also Chevalier, 1975, Fig. 211). Epitheca forms few millimeters below the margin of the corallite wall which bears costae ( Fig. 1A View Fig ).

Polyp tentacles retracted towards the oral disc during the day ( Fig. 8A View Fig , 9A View Fig ). Mantle vesicles smooth ( Fig. 9A View Fig ), polyp colours varying from light brown, or orange to bright red.

This species lives in semi-protected to protected environments and strives well in low light and high turbidity conditions.

Geographic distribution. This species has been recorded from the Red Sea, the Indian and western Pacific Ocean (see above mentioned references).

Description. Blastomussa wellsi forms phaceloid colonies by extra-tentacular budding ( Figs. 1D View Fig , 7D View Fig ). Although corallites are normally regularly spaced, recently budded ones can still have connections and coralla may be partially cerioid. Corallites are round to oval and 8–13 mm in largest diameter ( Figs. 1D View Fig , 7D View Fig ). Four cycles of septa are present, the first three reach the columella and are equal or sub-equal as the first can be slightly thicker, the third is reduced or incomplete ( Figs. 1D, E View Fig , 7D View Fig ). Septa are composed of multiple fan systems thus margins are lobed ( Fig. 1E View Fig ) ( Chevalier, 1975, Fig. 213). Septal margins and sides finely granulated ( Figs. 1E, F View Fig ). Columella formed by trabecular processes from the inner margins of septa and by papillae in the center. The papillae are often fused to form a lamellar structure in the middle of the corallite, which gives the columella a bilateral symmetry ( Figs. 1F View Fig , 7D View Fig ). Epitheca forms a few mm below the margin of the corallite wall, which bears costae.

Polyp tentacles retracted towards the oral disc during the day ( Figs. 8D View Fig , 9D View Fig ). Mantle vesicles rugged and sometimes of lighter colour ( Fig. 9D View Fig ), polyp colours ranging from light brown, or orange to bright red, and sometimes with green orals discs ( Fig. 8D View Fig ).

This species lives in wave-exposed environments. In New Caledonia it was only observed below 15 m deph in welllit outer slopes.

Geographic distribution. This species has been recorded from the Red Sea, the Indian and western Pacific Ocean (see references mentioned above).
