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
(

(d–e)) Tylostyles (occasionally subtylostyles) straight or slightly curved, dimensions: 141.3–414.8–674 (

(
