Pseudosuberites carnosus : Koltun 1966 , p. 99 , fig. 72, pl. XXXIII, figs. 3, 4 Description ( Figure 6 (a)) Sponge is branching-erect, provided with a stout peduncle. The consistency is moderate elastic and soft. Even surface covered with thin dermal membrane. Small oscula (average 1 for each branch) scattered through the surface and covered with outgrowths of dermal membrane. Colour from beige to dark-brown. Skeleton ( Figure 6 (b), 6(c)) Main skeleton formed by quite loose longitudinal spicule tracts and single spicules. Near the surface small tylostyles more or less radially arranged, forming spicule-brushes which are supporting dermal membrane. Spicules ( Figure 6 (d–e)) Tylostyles (occasionally subtylostyles) straight or slightly curved, dimensions: 141.3–414.8–674 ( n = 25) × 5.3–8.5– 11.8 µm ( n = 25). Distribution European waters of Central and North Atlantic, Norwegian Sea (near the coast of Iceland and Norway ), south-western and western parts of Barents Sea, west of Spitsbergen, Sea of Japan (Strait of Tartary).
