Description. Macroscopic features. Specimen irregular button shape about 1.6–1.7 cm in diameter by 6.9 mm (Fig. 12 A). No papillae present; however, one or more may have broken off. Colour in alcohol “yellow-brown”. Microscopic features. Skeleton composed of a palisade of megasleres, many with rounded tips protruding from the surface. Longitudal tracts of megascleres radiate out through the choanosome to end at the base of the ectosome (Fig. 12 B). Spicules. Spicule complement includes exotyles (Fig. 13 A), two classes of tylostyles (small, Fig 13 C, D), (medium, Fig. 13 E), large subtylostyles (Fig. 13 F), and raphides (Fig. 13 B). Megascleres in the ectosome include exotyles which have a granulated head ranging from stylote to tylote (Fig. 12 C, D). They are strongylote rather than stylote at the other end. Small styles to tylostyles occur in the ectosome (Fig. 13 C) while large subtylostyles form the longitudinal tracts in the choanosome (Fig. 13 D). Additional medium size tylostyles occur between the tracts (Fig. 13 E). Raphides bundled in trichodragmata (Fig. 13 B) were found in samples from four different locations in the specimen.
