( Fig. 29 A–F) Examined material. Sample Bugor 310: Indonesia , North Sulawesi, Siladen Island , Siladen Barat, 7 m , 28 January 2007 . Description. Gelatinous, very thin encrusting sponge (about 1 mm thick) on Carijoa riisei ( Fig. 29 A, B). Brownish-orange in situ ( Fig. 29 A), yellow-whitish in ethanol ( Fig. 29 B). The collected specimens consist of six fragments of a colony of Carijoa , up to 14 cm in length ( Fig. 29 B). Skeleton. No specialized ectosomal skeleton. Plumose tracts of mycalostyles, reinforced by toxas, without evident direction ( Fig. 29 C). Anisochelae scattered in the tissue. Spicules. Thin mycalostyles generally straight, with oval, needle-shaped heads and blunt tips ( Fig. 29 D), 125 – (194.8 ± 25.8) – 212.5 x 2 μm. Anisochelae with a characteristic tooth on the frontal basal ala ( Fig. 29 E), 12.5 – (13.6 ± 1.7) – 17.5 μm. Toxas with a well pronounced central flexion ( Fig. 29 F), 62 – (174.0 ± 82.4) – 380 μm. Remarks. The attribution to the subgenus Carmia is uncertain due to the bad preservation of the specimen. The presence of an ectosomal skeleton is doubtful. Mycale (C.) toxifera ( Dendy, 1896 ) is very close to Mycale (Carmia) sp. especially in the shape of mycalostyles, but the microscleres are different in shape and dimensions (see M. (C.) cf. toxifera description).
