Sponge pyriform, elongate, more or less laterally compressed, up to 40 mm in length, 5 mm width. The upper parts of the body are rather broad, lobate, sometimes branching, gradually narrowing towards the pedicle (Fig. 4h). Usually there is a single conical osculum on the sponge’s apex. Surface smooth. Consistency is fairly soft, delicate. The color is yellowish (in alcohol). Spicules . Styles (tylo- and subtylostyles) straight, rather short-pointed (sometimes blunt), of one size class only (W = 0.98, p ...
