Reniera fulva Topsent, 1893 , 39; 1925, 711; Griessinger 1971, 138, 139, Fig. 7, Fig. 8, pl. II, Fig. 3 . Haliclona (Halichoclona) fulva ; Kefalas & Castritsi-Catharios 2007, 1534.

Material examined. ESFM –POR / 2014–003, October 2013, 30 m, on a mussel shell in sandy bottom, 1 specimen Description. The specimen is massive and thickly encrusting. The body has a greenish color in alcohol; fragile and hard ( Fig. 2 C). Oscules are few, slightly elevated, circular and small (2–4 mm). Ectosomal and choanosomal skeleton consists of primary multispicular and secondary unispicular tracts ( Fig. 3 C). The choanosomal primary columns are covered by large quantities of spongin and thus are very difficult to distinguish. Spicules are include only slender and fusiform oxeas: 180–300 x 5–9 µm ( Fig. 4 C). No microscleres.

Habitat and distribution. The species was found on a mussel shell in the Black Sea. It was previously reported on hard substrata in shallow water in the east Atlantic Ocean ( Topsent 1892a, De Weerdt 1987) and the western Mediterranean ( Topsent 1892b), Adriatic Sea ( Griessinger 1971), Aegean Sea ( Kefalas et al. 2003), Alboran Sea ( Maldonado 1992) and Levantine Sea ( Evcen & Cinar 2012).
